[...]we are currently migrating from a rather old development version of Cocoon (december 2002) to the latest stable release 2.1.3. The increase in performance is awesome, but unfortunately we are facing reproducable faulty behaviour when load testing the actual version. After delivering roughly
20000+ pages without an error, the server starts sending back error 20000+ pages
with status code 500.
This is the configuration we use for testing: Sun Fire V480 (OS 5.8) with 2x 900 MHz, 4 GB RAM, Cocoon 2.1.3 (with Xalan as XSLT processor), Jetty 4.2.12, Sun Java 1.4.2_02-b03. We do the load testing with the tool "Siege" (version 2.56) with 40 concurrent users requesting 2000 pages each.
Try switching to Tomcat (or else) instead using Jetty. I've had a quite similar problem with Cocoon running on JBoss + Jetty under heavy load. Switching to Tomcat solved the problem.
