the server was running fine the last few months then suddenly today and yesterday it just stop responding and returned the 503 error. it works when i restarted the server but in a few hours, it stops again and returns the 503 error. The problem is i don't know what causes the problem time to time. i checked the error log and the file size is too large; could this be the problem of the sudden error on the tomcat server?
Any Help Will do
