We've got some strange issues with Tomcat locking during multiple requests/high load. We are using Tomcat as the sole web server (not behind Apache) to run a Servlet based web app. I've got the thread pool turned on with 10 threads. There is only ONE database method that is synchronized and a few Corba calls. We are using Sun's JDK 1.3 on Linux 6.x and Tomcat 3.1. Here's a scenario that locks it up EVERY time. I start 5 browsers on one machine and log in via all 5. I start 1 browser on another machine (via KVM switch) and log in. I simultaneously post two processor intensive requests (I'm using two mice :) ) via the two machines, then make a request with each of the 4 remaining browsers on the one machine in very quick succession. The entire server seems to hang whenever (and only when) one (or more) of the requests hits a synchronized method. Even static content is inaccessible at this point. I've read a couple of hints that there are some thread synchronization issues in JDK 1.3. Could this be the problem? Is this a known issue with the Tomcat version I'm using and should I upgrade to fix it? Thanks for any help you can give. -Devon -- Devon C.
