Symptoms

At times it is possible to observe several Siebel object manager component tasks hanging in "Handling Logon" or "Cleaning Up" status without progress.
As the number of tasks in "Handling Logon" or "Cleaning Up" status increases it is also observed an increase on the number of busy threads on the Apache Tomcat JVM for Siebel Application Interface.
The end users may receive a generic HTTP 500 or "Server is Busy..." error on the browser window.
The end users try to re-login by closing the browser window and retrying, but the Siebel application does not respond and several users are impacted at the same time.

STEPS

The issue can be reproduced at will with the following steps:
1. Try to login to the application, it may not respond immediately
2. The generic HTTP 500 or "Server is busy..." error may be returned after a little while
