Sure Sudhakar.Thank you for the response.Could you please help us resolve the same.This issue has been happening @Production environment and the users are severely impacted.
Hi, Session should get invalidated by the application server. Please check the Tomcat version if it has any similar bug register with this?
Hi,
This error can occur when a user attempts to click on an action from a browser session which was established in the prior running instance of the JVM. When Pega cannot locate the user's requestor (and it is not present since it was present in the previous running JVM) - this error occurs.
