Hi, I have been doing tests with bitcoind version 0.6003 And for mosts tasks it works ok, however when I run a shopping cart, the bidcoind daemon crashes after a while, no money is lost, no addresses are lost, it simply crashes after about 1 hour of use, if it is being used lightly manual transactions and no shopping cart, it works fine.

This bug can be reproduced by running the shoppping cart oscommerce and the weex module, however I do not think the bug is in the shopping cart module since all it is doing is using the same bitcoind daemon to check transactions repeatedly, and most of the time it works, if fails when the bitcoind crashes.

There is another minor bug, that at times it takes a long time to do a simple transaction like bitcoind getinfo, most of the time it takes less than a second, but randomly sometimes takes almost a minute.

To simply debuging, I compiled bitcoind without optimization, and debug enabled:

Here is the console error log at crash, not the name of the daemon was bitcoind6003-notoptized-debug, meaning it has no optimizations and debug enabled:

./bitcoind6003-notoptized-debug -server -debug

Has anyone had similar problems with recent versions of bitcoind, and what was done to fix it?

After doing some research, it appears that this bug depends on the wallet being used, with a clean new wallet it seems to be fine, however when I used my own wallet that has been around about a years and has gone though many bitcoin updates, I have a feeling is something on my wallet that causes this bug to trigger, and only happens are moderate or heavy use of bitcoind.

To usefully debug this issue, we need function names/line numbers from those addresses in [backtrace]. I think you find these out this using the addr2line command and the (debug) executable.

Function names/line numbers will help. I can also try to reproduce this running under 'valgrind' -- can you tell me what operating system you're running on and send me the output of:

grep 'method=' ~/.bitcoin/debug.log | tail -500

... so we have an idea of what RPC calls might be triggering the bug?

Hi Gavin,

I will do that, but it takes time to reproduce the error, I appears that it depends o the wallet being used.

once I reproduce the error I will send you the output of:

grep 'method=' ~/.bitcoin/debug.log | tail -500

Wladimir suggested using addr2line, and it is on my system, however I have never used it before, but I can give it a try.

It was compiled on a debian 64 bit system version 6.0, the compile was done statically, since the goal was to use it on a Centos 64 bit version 5.5, the errors occurs when running on Centos, I have not tried to reproduced the error under debian, but I could try. The reason it was not compiled on Centos directly was that Centos is supplied with an incomplete openssl that has missing code such as ecc, not only that even though boost, and openssl compile just fine under centos, too many errros in regards to those libraries are trigered at compile time, in centos the bigger problem is ssl, that is why it is compiled under debian statically.

The bug only triggers with moderate or heavy use, it does not trigger under light use.

As soon as I have the debug information that you need, I will send it to you.

Thanks,

Sergio Riveros

If I can be of any further help to troubleshoot this bug please let me know, I have a feeling that it relates somehow to the wallet, since with a clean new wallet this proble does not occur.

Sincerely,

Function names/line numbers will help. I can also try to reproduce this running under 'valgrind' -- can you tell me what operating system you're running on and send me the output of:

grep 'method=' ~/.bitcoin/debug.log | tail -500

... so we have an idea of what RPC calls might be triggering the bug?

in regard to using addr2line, can you provide a few instructions on how to use it, and how to submit the binary of bitcoind with debug enabled?

I've never used addr2line either but you can mail me the exact executable that caused the error at laanwj at gmail.com and I'll give it a try.

Seems that it happens after Base64 decoding (called from HTTPAuthorized), when constructing the string from char array. Doesn't help us much, I'm afraid... some time before this allocation the heap got corrupted. This could be in Base64Decode itself, or before that...

Is this still an issue with more recent versions (0.8.2)?

Closing due to inactivity.
