Unicorn server crashing worker with minimal backtrace

Question

I'm experiencing unicorn server worker random crash with this backtrace. I got it via gdb (bt command) and core dump.

#0  0x00007f2f525830c2 in select () from /lib/libc.so.6
#1  0x00007f2f5343025c in thread_timer () from /usr/lib64/libruby19.so.1.9
#2  0x00007f2f530d0047 in start_thread () from /lib/libpthread.so.0
#3  0x00007f2f5258928d in clone () from /lib/libc.so.6
#4  0x0000000000000000 in ?? ()

Any ideas how to get more info?

This is probably not the thread you are looking for (some other thread has crashed).

This GDB command may help you find that other thread: thread apply all where.
