Re: Memory usage in Tomcat 6
9 out of 10 are the heap size problem. Changing the -Xmsnm and -Xmxnm in the tomcatw.exe if you are using Windows. On the 32-bit Windows, you can only allocate 1.2 GB max. If you still have problem, check all the static vars to see any objects are growing forever. If you still have problem, there must be some huge objects created from time to time. You need to use tool like figure it out.

From: Billy Ng [mailto:[EMAIL PROTECTED] Subject: Re: Memory usage in Tomcat 6 Changing the -Xmsnm and -Xmxnm in the tomcatw.exe That's tomcat6w.exe, not tomcatw.exe. If you still have problem, there must be some huge objects created from time to time. It can also be PermGen space (classes) that is full, rather than the normal heap. Other resource exhaustion (e.g., file handles) can also cause OOMEs on occasion. You need to use tool like figure it out. Yes, a profiler - or even JConsole - is very useful here. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

From: Tuan Quan [mailto:[EMAIL PROTECTED] Subject: Memory usage in Tomcat 6 Hi all, how do I adjust Memory allocation Tomcat 6, running as service in Windows? Use the tomcat6w.exe program in Tomcat's bin directory. Read the FAQ for memory usage information: http://wiki.apache.org/tomcat/FAQ/Memory JConsole (part of the HotSpot JVM SDK) is a good tool for monitoring memory usage on the fly. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
