Hi guys, This is an old thread... but the problem still persists in my server. I get an 503 Error every 4-6 hours.
Do you think it's still load related? I have been updating the Apache Tomcat OpenBD Properties - Java Tab. and Change the Initial Memory Pool to 1GB. And the Maximum Memory Pool to 4GB. Also the Thread Stack Size to 256KB. Is that sufficient? How do I findout for sure what is the problem? Appreciate your help!
