Many thanks, Craig, Aravind and Shaun, for your comments. They are most
appreciated.
I set the TOMCAT_OPTS to "-server -Xms64m -Xmx192m" as you suggested
Shaun... I wasn't aware of the HotSpot application, I'm now reading up in
it. Thanks for the tip.
Unfortunately, I still cannot launch a 7th Tomcat process, and I don't
understand why not. I feel I'm missing something, but I just can't figure it
out. 6 works, but adding a seventh raises the OutOfMemoryError.
It does appear from the console output that Tomcat fails when it tries to
start a PoolTCPConnector. I start two connectors for each application (ie,
Tomcat process), one is an Ajp13ConnectionHandler, the second an
Ajp12ConnectionHandler which I understand is required for Tomcat to be
closed down.
I've included one of my server.xml files below, just in case there is a
glaring error in there. There's an xml for each application, they are all
the same except for the different ports I've assigned, and the log and work
file names etc.
Any further suggestions would be most appreciated, I'm have a minor heart
attack at thought of having to buy one server for every 6 small jsp
applications I want to run!
Thanks, Max Hugen
