[Snort-devel] Snort 2.4.3 perfmonitor not finishing log entries properly

Yes, sending snort a SIGTERM in the 2.4.x code base
caused Snort to exit right then and there (after
logging a few exit messages).
When the perfmon logging is interrupted by the signal,
control never returns from the sig handler.
This has been addressed in the 2.6 branch that was
announced yesterday. It catches the SIGTERM, but does
finish processing the packet it was working on at
the time -- then exits.
