I have multiple webservers (mostly the same exe's, with a few unique webservers) running under nginx, and they become non-responsive for anywhere from 30-120 seconds (more or less). Anyone have tips on how to figure out what is going on? They might run for weeks(this is the norm) without incident or it could be days(this is unusual), I see no sign of the webservers restarting, via the performance page. I have a monitoring script, that emails me when they become non-responsive, but I'd like to figure out what the issue is to remove the false positives. The unique webservers, just run and I never have an issue with them.
