Title: core dumps from bitcoin-qt 0.8.2 Post by: lano1106 on June 12, 2013, 02:38:55 AM It happens every five/ten minutes. Here is what is in my journal log file. I will recompile it without striping out symbols to have a nice call stack but in the meantime, if it is a known issue, please point me to possible workaround:

Title: Re: core dumps from bitcoin-qt 0.8.2 Post by: lano1106 on June 18, 2013, 07:50:42 PM interesting suggestion.
I was under impression that 0.8.2 was the latest and greatest. Anyway, my investigation has advanced a little bit.: #0 0x00007f11d50df3d1 in _int_malloc () from /usr/lib/libc.so.6 (gdb) where #0 0x00007f11d50df3d1 in _int_malloc () from /usr/lib/libc.so.6 #1 0x00007f11d50e261a in calloc () from /usr/lib/libc.so.6 #2 0x00007f11d8a2d340 in ?? () from /usr/lib/trickle/trickle-overload.so #3 0x00007f11d8a2d922 in select () from /usr/lib/trickle/trickle-overload.so #4 0x00000000004e3926 in ThreadSocketHandler() () #5 0x00000000004e4a3d in void TraceThread<void (*)()>(char const*, void (*)()) () #6 0x00007f11d7337a09 in ?? () from /usr/lib/libboost_thread.so.1.53.0 #7 0x00007f11d7115b52 in start_thread () from /usr/lib/libpthread.so.0 #8 0x00007f11d515893d in clone () from /usr/lib/libc.so.6 If you core dump deep inside libc while allocating memory, that can only mean 1 thing: Heap corruption Will run valgrind on bitcoin-qt to see what it finds. If valgrind finds something easily, I'll be a bit surprised as this should be a mandatory check before bitcoin dev team release a new version.

The problem was in trickle that I am using to stop bitcoin-qt to upload 20-30 GB of data daily! http://monkey.org/~marius/pages/?page=trickle https://wiki.archlinux.org/index.php/Trickle If there are other trickle users here, you are likely to experience the same core dumps with bitcoin-qt 0.8.2, you can find a description of the problem and a patch file to fix the core dumps here: https://bugs.archlinux.org/task/35872 If this helps you, BTC donations are welcome |
