heap size with Tomcat 3.2.3 !!!
Which JVM are you using?
On Windows 2K w/ SP2 I found that the Sun JDK 1.3.1 server hotspot JVM
crashed and burned running Tomcat 4.0.1 this way within 24 hours easily.
A few others emailed me about it also.
Switching to the Sun JDK 1.3.1 client hotspot JVM magically
Hello,
Before my manager insists that we switch to JRun, can any of the Tomcat
developers help with a problem of an ever increasing heap size of the
Tomcat java.exe. ?? (We are running Tomcat 3.2.3 and JRE1.3.1. and the
IIS redirector)
We are running a load test using LoadRunner scripts
.
Thanks,

and swap settings yet? Because
each JVM uses its own completely separate heap space, it's quite easy to
run out of either physical memory or swap space -- once that happens, it
doesn't matter how big you set Java's heap size to be, because the OS
won't be able to satisfy it anyway.
A quick way
Where is this command line to set the maximum heap size located? Please
help, I am kind of new to this staff!

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
When you set the TOMCAT_HOME and JAVA_HOME variables, also set a third
variable called TOMCAT_OPTS with the value -Xms256m to up your initial heap
size. This sets your initial memory allocation for the JVM that Tomcat
runs from. I'm running a system with almost identical specs to yours
