I am using Phusion Passenger 2.2.2 having a Rails 2.3.8 and a pair of.3.2 applications. Once in some time it'll freeze and there's no response in the server when attempting to gain access to the rails programs. There's nothing within the apache log or even the rails logs. I am not speaking in regards to a 500 error or anything, there's just no response whatsoever. They do not respond until we restart apache.
I attempted to follow along with these instructions to get a stack trace: http://www.modrails.com/documentation/Users%20guide%20Apache.html#debugging_frozen
I sent SIGABRT towards the processes, based on the instructions, and they didn't appear of looking after. Did not see anything within the apache or rails logs.
