I'm having an issue with an in-house processor (not for email inboxes).
Only seems to happen periodically on heavy loads, not in dev environments.
Based on the stack trace the Illegal self-suppression is happening in the
framework code and it seems to be masking the original exception that was
thrown (maybe?).
Going to be continuing to trace this one down but was wondering if anyone
has seen something like and what might be the likely cause.
