Intermittent errors with PAM when reading emails

Products

• CA Process Automation Base

Issue/Introduction

For a little over two weeks we have intermittently with the operator that reads the mailboxes that are used for automations, the error that it throws is the following:

Failed to execute operation to retrieve list of mails - Could not connect to the Mail Server Remote host closed connection during handshake;
   nested exception is:
  javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake

We validate with the server administrator team and they certify that the failure does not originate from there.

Environment

Release : 4.3

Component : Process Automation

Resolution

Recommend to use the Wireshark utility to analyze network traffic between the ITPAM server and the email server to determine where the connection is being reset.
