Actually I think "robustness" is the key here (in this context it means that the locks of a thread / processes are released if a thread / process dies unexpectedly (crashes)); It is very likely that in your case the PHP process with FPM SAPI module dies while holding a lock shared between processes and the other processes get stuck waiting for this lock to unlock. _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
