RE: Tomcat hangs up from time to time
I just finished dealing with the same problem. In the end I ended up having to install a new version of linux (rh 9 - rh enterprise) to resolve it. I'm not sure about the exact cause, but given that the problem acts like a socket problem (Hard to tell without errors) I'm guessing that that would be a good place to start looking. Please let me know if you find anything.

Check your JVM documentation, and then kill the main Tomcat process with the signal that causes a thread dump.

Tomcat hangs up from time to time
Hi all, Lately, I have set up Tomcat 5.5.7 on Slackware Linux 9.1. I have configured four virtual hosts for me and my workmates. We develop a few web apps with Struts, Torque, Velocity, etc. Application base directories, scratch directories and tomcat logs are located on NFS share. Common approach is edit source, compile, reload web app with org.apache.catalina.ant.ReloadTask, look at browser time and again. But about two-five times per day, Tomcat hangs up, java (version is 1.5.0_01-b08) eats much cpu (up to 90%), and no any response from Tomcat, no warnings/errors in logs. I even can't stop it with shutdown.sh! Have anyone the same problem? Any solutions, advices, thoughts? Thanks. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
