OutOfMemory exceptions

[Ryan Daly <da...@ctc.com>]

All:

I've seen a few threads regarding the OutOfMemory problems.  Has it been
decided that reloading webapps is one of the causes of this?  And, if
so, would an undeploy and a new deploy fix that issue?

Thanks.

Check the memory usage of your Tomcat server using the manager application. 
Should be under the Server Status option. This will give you a line something 
like this:

JVM
Free memory: 1017.68 MB Total memory: 1023.93 MB Max memory: 2047.93 MB

Normally the JVM is set up to only use 64MB of memory by default.

Add the following line to your catalina.sh file (Unix/Linux):
CATALINA_OPTS="-Xincgc -Xms1024m -Xmx2048m"

Or add the following line to your catalina.bat fil (Windows):
set CATALINA_OPTS="-Xincgc -Xms1024m -Xmx2048m"

I put this just under the JAVADIR line in that file (which is line 50 in my 
file). Restarted tomcat and all my memory messages went away.
