Application hanging in production! New Relic Phy Mem Utilization Haywire! Help!

Hi all,

My app was doing fairly well in production past couple a months. But past 2 days, its gone off its rocker! Not able to figure out what the problem is. The symptoms are as follows..

- It first went down when I deployed and ran a migration yesterday. A simple column addition to a table - The production log showed the SignalException::SIGTERM error ( dont know anything about it ) - a server reboot seems to solve the problem temporarily - New Relic RPM shows wayward physical mem utilization. - im on Slicehost and the 'free' command shows way too much SWAP memory usage (which is basically not good)

Does it sound like im having a memory leak? anywhere i could look? anything i can do?? Oh those who have fought the battle and come out victorious.. bestow upon me ur knowledge! :smiley: Seriously.. any pointers?

Thanks!

Hey blasterpal, already on it! more information in case u can help. I run a cron on my server which basically accesses a particular URL in my Rails app which performs some tasks. it seems to take loads of time.. and when i drill down in New Relic, the following line is thrown up..

   Dependencies.new_constants_in(Object) { super }

this is a line from active_support

File: /Library/Ruby/Gems/1.8/gems/activesupport-2.1.0/lib/ active_support/dependencies.rb

i saw a couple of error throws caused due to dependency loading from active_support in my production log earlier yesterday during initial analysis.

Any more ideas? - Hide quoted text -
