bitcoin-qt hangs during shutdown #2690

bitcoin-qt 0.8.2rc1 and rc2 often gets stuck during shutdown. I have experienced this with Fedora 18 x86_64 native builds. In both of these hangs, kill -9 is required. bitcoind is unaffected by these hanging shutdown issues.

Type 1: Flushed X addresses to peers.dat Loops Forever warren [13:05:06] sipa: Looping "Flushed 12035 addresses to peers.dat 38ms" messages forever after *coin-qt is told to Exit. kill -9 required. sipa [13:05:22] something is blocking cs_main sipa [13:05:41] addrman functions without cs_main, so continues to dump peers to disk

Type 2 Hang addcon thread interrupt dumpaddr thread stop msghand thread interrupt net thread interrupt connection timeout opencon thread interrupt

Any RPC calls being done before shutdown?

No RPC calls.

Can you run under the debugger, reproduce the hang, and then see which threads are left running?

I did a lot of stress-testing of shutdown (mostly on OSX), and haven't seen shutdown hanging.

I gave sipa a "thread apply all bt full" yesterday and he didn't see anything unusual. I'll get back to this later today.

My users report nobody is getting this hang on Windows or Ubuntu, only on Fedora 18 x86_64. This is quite frustrating. I will try to get stack traces today.

Doesn't happen for me on Fedora 17. In any case, try bisecting to figure out which commit caused it.

Have Qt poll for shutdown requested, the QT way.

Still gets stuck with this build.

commit b31499ec72edd1554d4612d1b54808fce0360e14 Author: Gavin Andresen gavinandresen@gmail.com Date: Sat Mar 9 12:02:57 2013 -0500

Clean up shutdown process

This build gets stuck during exit with the looping address dumping to disk. kill -9 is required.

Port Thread* methods to boost::thread_group

This fails to build.

commit 72f14d26ecc67a210a29d7914e580b8e67e45d8e Author: Gavin Andresen gavinandresen@gmail.com Date: Fri Mar 8 20:19:17 2013 -0500

LoopForever and ThreadTrace helpers

This build exits fine without hanging.

What version of boost do you have? Sounds like your boost::thread_group::interrupt_all is buggy.

Gavin Andresen .

boost-1.50.0-5.fc18.x86_64 libdb4-4.8.30-5.fc18.x86_64 openssl-1.0.1e-4ec.fc18.x86_64

I thought the gitian builds were hanging during shutdown, but I can't reproduce that now. Seems limited to Fedora 18's boost.
