I recommend focusing on solving that silent termination problem. There
are two general reasons for silent deaths: Polygraph bugs and running
out of system resources. It is usually possible to figure out what
exactly is going on. Enable coredumps. Test that they work by sending a
running Polygraph server process SIGABRT. Check system logs. Etc.

Once that server death becomes less "silent", either report a Polygraph
bug (with that information at hand) or adjust system resources/workload.

Good luck,
