I am not sure I understand this one.
I am kinda restricted on the deployment machine (the linux machine
mentioned above) - it was developed on a Solaris 9 machine and moved
over - everything works pretty normal 'cept this freezing problem. Same
versions of all software on both machines tho
(java,mysql,tomcat,struts).
I can ask the admin to give me the output of it the next time it
freezes (we are periodically restarting it right now via cron just to
make sure there is as little downtime as possible).
Thanks again.
