Hi,

I'm currently integrating a SOAP-based middleware on Tomcat (5.5.9) with
Sun JDK 1.5.0_02 and get into problems when using maxThreads with a
value greater than 500.

Tomcat locks up completely without getting back to normal operations
after a while. No exception or error is reported in the logs, it just
stops. All connections are refused after the lockup. Tomcat has enough
memory (>1GB) assigned with the JVM options.

If I use maxThreads="500", the server runs fine, but 500 is not enough
for my project ;-(

I tried to increase the stack size, but this doesn't help..

The connector is defined as:

<Connector port="8888" maxHttpHeaderSize="8192" maxThreads="500"
   minSpareThreads="50" maxSpareThreads="150" enableLookups="false"
   redirectPort="8443" acceptCount="200" connectionTimeout="20000"
   disableUploadTimeout="true"/>

If I change 500 to 700 or more, Tomcat locks up. Is this a Windows
problem?? 

Hardware is not an issue, I think.. (dual Xeon 3,4GHz, 4GB)..

Thanks,
Michael
