I'm doing some testing via cfuse (technically via samba-over-cfuse). I caught the core dump and pulled a stack trace. This is the thread that seems to be initiating the core dump. I can provide the rest if it'll help identify what's going on. My cfuse crashing thread: Thread 1 (Thread 1696): #0 0x00007f14ede7d38b in raise () from /lib64/libpthread.so.0 No symbol table info available. #1 0x0000000000553fe9 in handle_fatal_signal(int) () No symbol table info available. #2 <signal handler called> No symbol table info available. #3 0x00007f14eccb29b5 in raise () from /lib64/libc.so.6 No symbol table info available. #4 0x00007f14eccb4195 in abort () from /lib64/libc.so.6 No symbol table info available. #5 0x00007f14ed557aad in __gnu_cxx::__verbose_terminate_handler() () from /usr/lib64/libstdc++.so.6 No symbol table info available. #6 0x00007f14ed555c36 in ??
