Email listener stops processing sporadically



Email listeners stop processing emails sporadically. To overcome this, the user must restart the node. On stopping or restarting the Listener, the Run status updates to 'Stopping', and the system hangs.

Root Cause

A defect in Pegasystems’ code or rules.

On debugging the '', it was determined that the email listener was still processing an email.
According to the Producing Thread dumps while the Listener was in the stuck state, the Listener was waiting to receive a response to initiate an SSL handshake for a REST call that was made. There was an underlying network issue, due to  which a response was not returned to the application. However, there was also an issue with the Pega application where the Connection attempt was timed out incorrectly.
