Avoiding tomcat crashes or do auto restarts?
Platform: Intel PIII, RedHat 8,
IBMJava2-SDK-1.3.1-3.0,
tomcat4-4.1.18-full.1jpp
We have found that if we push the server too hard, the Java VM running
tomcat crashes. I'm assuming it's running out of memory, or file
descriptors, or somesuch.
Does anyone have a solution to this type of problem? Config
parameters that can be tuned? A watchdog process that will restart
the Java VM if it crashes (ie. something like the apache httpd does)?
A temporary problem caused by a restart is acceptable.
Flatlining due to a VM crash isn't.

Tomcat largefile option in web.xml
Posted by Giorgio Ponza <gi...@opla.it>.
Hi all !
I have a question about the largefile in the default web.xml
I've set the value of largefile to TRUE, but i can't see any
differences, temp files, etc.
There are some FAQ for this option?
Tx

If you run "java -X" you should get a list of memory orientated options.

This maybe of help. Increasing the Memory allocated to the Java VM when it
runs Tomcat is probably the solution.
