stability issues after switching from windows to linux

[mpruett]

Hi i have been using subsonic for a few years on my windows server with out any issues, i have recently switched to Linux Mint and have run into some stability problems with subsonic, after about about 3 or 4 hours of uptime it becomes non-responsive and i can not even bring up the web page, if i try restarting the service it will restart just fine but after the restart when i try accessing the webpage i get the following error:

HTTP ERROR: 503

SERVICE_UNAVAILABLE

RequestURI=/

Powered by jetty://

a reboot will resolve and allow access to the site but then in about 3-4 hours it will crash again, the following is what i see in the log, and am unsure what is causing this, any help would be much appreciated.
