Hey guys, I'm getting signal 6 during sqlite_step in WAL mode. Working on Ubuntu 12.04, sqlite3 3.7.9. One process is the writing continuously, while other process reads from the DB in a multi threaded access. I made sure that sqlite is configured to serialised mode.
Here is the backtrace: #0 0x00007f4f78f0d08d in nanosleep () from /lib/x86_64-linux-gnu/libc.so.6 #1 0x00007f4f78f0cf2c in sleep () from /lib/x86_64-linux-gnu/libc.so.6 #2 0x00007f4f7982d881 in signal_catch (signo=6) at signal_masker.c:35 #3 <signal handler called> #4 0x00007f4f78e83425 in raise () from /lib/x86_64-linux-gnu/libc.so.6 #5 0x00007f4f78e86b8b in abort () from /lib/x86_64-linux-gnu/libc.so.6 #6 0x00007f4f78ec139e in ??
