Hello,
No problem for more information:
tomcat6w.exe:
java options:
-XX:+UseParallelGC
Initial memory pool: 256 MB
Maximum memory pool : 1024 MB
Thread stack size : 1024 MB
httpd.conf: (Only changes from default value):
ThreadLimit 1920
ThreadsPerChild 1920
MaxRequestsPerChild 0
Include http-vhosts.conf
server.xml
<Connector port="8010"
protocol="AJP/1.3"
connectionTimeout="30000"
redirectPort="8444"
request.useSecret="true"
request.secret="xxxxx"
maxThreads="10000"
tcpNoDelay="true" />
At the moment there are two cluster nodes. Both are virtual machines and have
installed a Windows 2003 Standard Server R2 in 32-Bit.
There is a Apache 2.2.14, mod_jk Connector 32-Bit 1.2.27, JDK 1.6 Update 17 in
32 Bit, Tomcat 6.0.20 in 32 Bit with tc-native installed.
All requests will be redirected from an hardware loadbalancer to the node 1,
and this node depoly the requests with Apache mod_jk to the underlaying Tomcats
on node1 or node2.

This is not a heap usage issue, despite the OOME being thrown. You're starting
too many threads in the Tomcat process, either reaching the predefined limit
for the OS, or running out of process space for the additional structures
needed by a thread (e.g., stack space).
Since you didn't tell us anything about the OS you're running on, the JVM
you're using, or your Tomcat and mod_jk configs, there's not much more anyone
can tell you.
