RTC hangs after I set javax.net.debug in Websphere
Recently I worked with a customer who saw significant slowness after enabling a Java flag to debug an SSL problem. The customer was using Websphere and Rational Team Concert 3.0.1.2. What happened?

The javax.net.debug flag can be set to debug SSL problems, but it should be unset (removed) as soon as the problem is recreated and the debug information gathered.
Leaving the flag enabled can cause lock contention that slows down requests. Because Jazz makes many secure requests to read information, this can cause Jazz applications to become unresponsive. The flag should be removed from any Jazz application it was added to (ie JTS, CM, QM, etc). Here are instructions: In the WebSphere Admin Console, go to Servers > Server Types > WebSphere Application Servers > server_name > Expand Java and Process Management (under Server Infrastructure) - >Process Definition > Java Virtual Machine > Custom Properties > Set javax.net.debug to false Save the change and restart the application.
