Steps to Reproduce

This happens intermittently in the production environments.

Root Cause

A defect in Pegasystems’ code or rules. HFix-10155 addresses the issue when requestor is returned to the pool after being "borrowed" before.  When it is retrieved again by a client calling "borrowRequestor", it is not re-initialized.


Apply HFix-24927. This solution modifies the "borrowRequestor" method to insure any requestor "that is not new" gets re-initialized.
