This exception happened to a production environment and it has happened again. It happens every now. I retry the operation but sometimes the issue persists.

Here is the error detail and the list of accounts where it happened is sent in a follow-up private email.

Please provide a solution ASAP.

Retrying the operation is a work-around BUT NOT A SOLUTION UNLESS YOU FIX THIS.
