Hello, If I were you, I'd load test your site first before going to production. As you pointed out, you cannot afford to stop your production server or hang it with OutOfMemory errors. This is good advice. Load testing is generally easy to do in development, and hard to recover from if you don't

Asim, kill doesn't work on Windows. Besides, I can't afford to stop the server right now. Many of our customers are using currently using the websites. In order to get a thread-dump, you can do a CRTL-BREAK (not CTRL-C) on win32. Unfortunately, you have to already have started the JVM on a c

Our sites have just went down for a couple of minutes. I solved the problem by restarting Tomcat. At the time of the crash, java.exe was about 345MB. I'm running tomcat with the -Xms128m -Xmx256m options. Our server has 1GB physical ram. On the Tomcat logs, it reads: 2004-02-27 16:58:55 Ap

My main concern is to make sure that there is no memory leakage of any sort. Our server has 1GB of ram. I'm running tomcat with -Xms128m -Xmx256m. In this case, I'm guessing that java.exe will eventually become 256MB + JVM memory ~= 370MB and stay stabilized like that. I don't want our serv
