Bitcoin-core multiwallets limited to about 300 loads #15291

    Hi, Using Bitcoin Core RPC client version v0.17.0.1-g1476554d3b1db5352c0de1de7524864d4bce3aac

    I’m using bitcoin-cli loadwallet and unloadwallet commands. They both seem to work fine. Unfortunately, memory is getting higher and higher, and no wallet can be loaded after 300 have been. The problem may be related to BerkeleyDB rather than to Bitcoin Core itself. Fact is that lsof shows handles not cleared off after the unloadwallet command is issued. Files still handled are .walletlock, db.log and database/log.0000000001 . When 300 different wallets have been loaded/unloaded, used RAM is over 8 GB, and bitcoind will finally become unstable and fail.

    Any help would be appreciated. Regards,

    Are you doing some stress test or are these load/unload done over a long period of time?

    Is the same wallet loaded/unloaded multiple times?

    Hi Joao,

    These load/unloads are done on a short period of time. We check hundreds of wallets for new transactions, so to feed a database.

    The same wallet may be loaded/unloaded multiple times, but one is enough
    the file handles won’t be released.

    unloadwallet behavior was changed in #14941, you could try that (it was also backport to 0.17 branch in #15002).

    Thank you for the reference. I’m going to give it a test. Agreed, an asynchrous unloadwallet can be useful (faster), but can also lead to disasters. I’ve always been surprised that BerkeleyDB 4 should be used, but that’s another story.
  6. promag commented at 3:57 pm on January 30, 2019: member
    @fscemama thanks, please let us know how it went.

    Hi, just stress-tested with today’s github master. Result is alas same. Basic testing: Firstly, load 30 wallets: j=0; for i in /wallets/*; do j=echo $j+1|bc; if [ $j -lt 30 ]; then bitcoin-cli loadwallet "$i"; fi; done Then, unload them: for i in /wallets/*;do bitcoin-cli unloadwallet "$i"; done Look for handles: lsof -p pidof bitcoind |grep wallet 89 lines, .walletlock, db.log, etc. As for memory, 1.5 GB are used by bitcoind. I must mention unloadwallet commands have taken no time to execute. Thanks !
  8. promag commented at 2:42 pm on January 31, 2019: member
    But do you see memory leak?
  9. fscemama commented at 2:57 pm on January 31, 2019: none
    I’m not sure about what is a memory leak. Surely, the memory footprint remains very high (1.5 GB for 30 loaded wallets, and no memory is released after wallets are unloaded). In fact, lsof return proves wallets db files still being open. Unloadwallet does not close DB files. BTW, loading one more wallet should not take 400+ MB of memory, there’s certainly something to optimize there, but that’s a drawback we can live with. I’m sorry, I have no C++ knowledge to give any useful help in code.
  10. promag commented at 3:06 pm on January 31, 2019: member
    If each wallet takes 400+ MB then with 30 wallets you would need much more memory than 1.5GB. Can you check memory usage after each loadwallet and then after each unloadwallet. You could test #15297 branch which closes those files?
  11. fscemama commented at 3:09 pm on January 31, 2019: none
    40-50 MB. Sorry, end of week!!
  12. fscemama commented at 3:11 pm on January 31, 2019: none
    I agree to test, please let me know when I can download the master. Then I’ll compile and let you know. The hack proposed in #15297 looks fine.
  13. promag commented at 3:18 pm on January 31, 2019: member

    It would help if you test that branch instead of master:

    0git fetch git@github.com:bitcoin/bitcoin.git refs/pull/15297/head
1git checkout -b pr15297 FETCH_HEAD
2make -j

    THANKS.

    Still unrelased handles. Sample output of the lsof command:

    0bitcoind 1568 root   37uW     REG      8,1         0   670564 /wallets/xxxx/.walletlock
1bitcoind 1568 root   38w      REG      8,1         0   670567 /wallets/xxxx/db.log
2bitcoind 1568 root   41u      REG      8,1   1048576   654805 /wallets/xxxx/database/log.0000000001

    I’ve considered the possibility of clearing off these file handles the kernel way, like this: echo -e "p close(654805)\nquit\ny\n" | gdp -p 1568 And this is not a good idea : BerkeleyDB will complain and this could lead to database corruption. Maybe I’ve missed something, the #15297 thread makes me feel like trying to google the BDB issue and try to patch it.

  16. fscemama commented at 6:25 pm on January 31, 2019: none
    I’m a newbie as for C++ and I may be wrong, but I’m not sure the closing of the WalletDatabase is ever called.
  17. promag commented at 6:32 pm on January 31, 2019: member
    Mind sharing the steps to reproduce here?
  18. fscemama commented at 6:38 pm on January 31, 2019: none

    No more than that:

    Basic testing: Firstly, load 30 wallets: j=0; for i in /wallets/*; do j=echo $j+1|bc; if [ $j -lt 30 ]; then bitcoin-cli loadwallet "$i"; fi; done Then, unload them: for i in /wallets/*;do bitcoin-cli unloadwallet "$i"; done Look for handles: lsof -p pidof bitcoind |grep wallet 89 lines, .walletlock, db.log, etc. As for memory, 1.5 GB are used by bitcoind.

  19. promag commented at 7:00 pm on January 31, 2019: member

    @fscemama are you sure you built #15297 branch? I can’t reproduce your case.

    Anyway, I’ll push a commit later testing that the files should not exists after unloadwallet calls.

    Really got it. Bitcoin Core RPC client version v0.17.0.1-g1476554d3b1db5352c0de1de7524864d4bce3aac

    My part of db.cpp:

     0void BerkeleyEnvironment::Close()
 1{
 2    if (!fDbEnvInit)
 3        return;
 4
 5    fDbEnvInit = false;
 6
 7    for (auto& db : m_databases) {
 8        auto count = mapFileUseCount.find(db.first);
 9        assert(count == mapFileUseCount.end() || count->second == 0);
10        BerkeleyDatabase& database = db.second.get();
11        if (database.m_db) {
12            database.m_db->close(0);
13            database.m_db.reset();
14        }
15    }
16
17    FILE* error_file = nullptr;
18    dbenv->get_errfile(&error_file);
19
20    int ret = dbenv->close(0);
21    if (ret != 0)
22        LogPrintf("BerkeleyEnvironment::Close: Error %d closing database environment: %s\n", ret, DbEnv::strerror(ret));
23    if (!fMockDb)
24        DbEnv((u_int32_t)0).remove(strPath.c_str(), 0);

26    if (error_file) fclose(error_file);

    Sorry, what gives ./src/bitcoind --version?
  22. fscemama commented at 10:31 pm on January 31, 2019: none
    For some reason, make install in master-bitcoin dit not overwrite /usr/local/bin/bitcoind. I’ve done it manually and retested. I confirm the file handles are cleared off. Memory footprint is not reduced, though.

    Releasing memory back to the system is often nontrivial due to fragmentation.

    The bigger question is whether if you first load 300 wallets, then unload them, and then load 300 (other) wallets, does the memory usage stay constant the second time, or does it go up further?

  25. promag commented at 10:46 pm on January 31, 2019: member

    Thanks for testing @fscemama and confirming the issue is fixed.

    Regarding memory, @sipa is right, a good test should use lots of non empty wallets (with lots of transactions and keys).

  26. fscemama commented at 11:22 pm on January 31, 2019: none

    Thanks @promag and @sipa for making Bitcoin Core better. Here are a few tests, which may help understand why memory is not released.

    So, you improved things with this branch. The wallet itself is completely released, and this does deserve to be committed. Now, I suspect the opening of these wallets needed blocks to be opened for rescanning of transactions, and that these blocks have not been released. This is going to be a more difficult patch now to release blocks needed by an unloaded wallet, and not by other wallets that may be loaded.

    Thanks a lor for being patient.

    this log reads too familiar for not attracting my attention….

    for the basics (and I suppose that’s what @sipa was after in his comment) unix based operating systems typically keep the contents of the memory until requested by another call. that’s what’s giving us the look-and-feel we are used to.

    so fighting the symptoms like it appears here might not be the best solution.

    so why familiar? we were looking at similar lines few months back and started tracing the issue. out of laziness we didn’t finish the trace as we couldn’t reproduce it on any other kernel/compiler combination than ours.

    findings on troubleshooting: while configuring our compiler, we’re asking it if it understands and can handle certain thingies like position independent code (PIC). typically, we will receive a “yes we can” answer. in the previous IF clause, the script decided to let the compiler apply the flags on demand by getting them passed through CXXFLAGS. unless we’re on windows. ironically, gcc decides against PIC, at least on the crypto libraries, we didn’t explicitly test against all (but bench would be a hot candidate)

    I think that after the #15297 hack, Bitcoin Core will be more stable when used in multiwallets context. I mean: the more memory you have, the more different wallets you should be able to use, given you load/unload without never reaching the ~300 simultaneous loaded wallets (unless you tweak BerlekeyDB settings and kernel semaphores, supposing this would work). Please, commit this to next official release, and I’ll give you a real-world, production-context feedback. @HashUnlimited : thank you for this analysis. I’ve always thought Bitcoin Core had been thought for a one-wallet use, and that BerkeleyDB had been chosen for easier cross-platform porting. I’m dreaming of a Bitcoin Core that would use an instance of Postgresql rather than BerkeleyDB, on a bitcoind setting. Why not after all.
