This smells like a Polygraph bug to me. Does this happen all the time?

Please email the answer and the following to bugs_at_web-polygraph.org:

- Web Polygraph version used.
- OS name and version.
- GCC version.
- Your exact workload file.
- Complete console logs from all clients and servers.
- The stack trace from the coredump.

I understand that some of the above may be unavailable or incomplete;
just do your best. The more info you can collect, the better our chances
are for finding and fixing the bug.

If you have a coredump file, you can get a stack trace using the "where"
command of gdb. If you do not have a coredump file but can reproduce the
problem, please consider changing your OS settings (e.g., limits) so
that coredump is generated.

Thank you,

Alex.
