Ahh jmeter on the same machine? I made very negative experience with that tool. For stressing my applications, I use the Microsoft Webapplication Stress tool: <http://www.microsoft.com/technet/treeview/default.asp?url=/TechNet/itsolutions/intranet/downloads/w ebstres.asp> It's from MS <spit>, but it's (ahem) good. > - The production server went into this state within 2 minutes of running a >scaled back version (6 threads) of the same jmeter test.

Indeed: How many RAM has your machine? - Don't set the -Xms parameter, I read that somewhere in a performace article. I have to update the Cocoon docs. - Don't set the -Xmx == RAM you have. Your machine needs some memory, too. - Set the heapsize always lower as the -Xmx paramter, otherwise your JVM can run out of Memory. - Don't set free memory that high, I think 10megs should be enough. Consider, this formel: if ((JVM totalMemory > heapsize AND JVM freeMemory() < freememory) == true) then the cleanup thread kicks in. Wrong settings can cause to many thread iteration. >Are you aware of any kernel or JDK version issues that may cause problems? Nope, unfortunately it's always the code ;-). >Thanks for the information! No problem, you're welcome. BTW: can you try the latest CVS, just for comparing? ~Gerhard ---------------------------- I just found the last bug... ---------------------------- --------------------------------------------------------------------- Please check that your question has not already been answered in the FAQ before posting. <http://xml.apache.org/cocoon/faqs.html> To unsubscribe, e-mail: <[EMAIL PROTECTED]> For additional commands, e-mail: <[EMAIL PROTECTED]>
