  Uh… that’s bad.  The Oracle client library grabs the signal handler for itself?  It’s not the cause of the crash, but it’s terrible practice.

  That’s the problem we’ve been fighting for a while.  Unfortunately, I can’t reproduce it here.

  What does the rest of the debug log say?  Knowing that might also help.  You could also try turning on DEBUG_STATE_MACHINE in src/main/process.c.  It will cause the debug output to print out state transitions for each request.
