Just wondering. With a 64 bits OS, how much RAM can you handle in a JVMand
therefore with each instance of Tomcat?
For a 12 Gb of RAM machine, it would be wise if you want to have this kind of
setup (Apache and two Tomcat instances in the same machine) if you need more
than 400-500

Hi,
we have the problem that tomact is slowing down after a while

Make a thread dump (kill -3 jvm pid). Information usually will be
written to catalina.out.
You can use jvisualvm tool to capture threads, memory snapshots, etc.

Start by taking a thread dump to find out what's going on inside the JVM.

Yes, there is a limit on heap size for 32-bit JVMs and it's usually around 1.5
GB depending on the OS.
On Windows 32-bit JVMs are often limited to less than 1.3GB of heap due
to fragmentation of the 32-bit address space. Sometimes one cannot even
get 1GB of heap!
For any hefty server process on Windows you really want a 64-bit JVM for
this reason.
On other OS's one can often allocate much

I was facing a problem with similar symptoms - Tomcat 7 (on centos 5, 64 bit,
12 GB RAM) was crashing without anything being logged in catalina.out
In case of JVM crash, there is supposed to be some hs_err_pid.log file but
that was also not getting generated.
Neither were there any OutOfMemory
Interesting and thanks for your response.
We switched back to VM version 1.6.0_07 (64 bit on Slackware) and everything
was fine. For several unrelated reasons, we switched to Tomcat version 6.0.35
and JVM (Oracle) version 1.6.0_16 and all has been fine for a month or so.

A Wicket app that is not written correctly can suck up resources. Wicket
keeps track of pages a user has been on by serializing them, back
button support. If a page has references to other objects, it

Wicket has many built-in
