Worker processes not shutting down

January 24, 2012 03:42PM
Following an upgrade from nginx 1.0.2 to 1.0.11 I've experienced a problem with worker processes that are not shutting down. When looking in the list of running processes the worker processes appears to be shutting down but never actually exits.

I've been using the ubuntu nginx ppa's for maverick.

As the worker processes doesn't shut down nginx ends up consuming to much memory and is ultimately unable to spawn new worker processes.

Below is a list of processes showing the problem:
