Re: RE: Tomcat Hangs
It appears that upgrade to JDK 1.4.2 is helping.

RE: RE: Tomcat Hangs
Hi, >Yes this time it appears to be a crash. The message that I posted below >is the only message that I can see on the console. This is the last >message before crashing. There should be a file called hs_err_ ( can be a number of different things on the Windows platform) in the current working directory of the JVM when it crashed. Look for that file and post its contents if you find it.
