Potential segfault when Message Routing Framework (MRF) messages cross from one TMM to another.


It is possible for the message object to be removed before the asynchronous operation completes. If this occurs, a segfault may occur and the system might restart.


This issue occurs when MRF messages travel from one TMM to another, and an asynchronous operation also occurs (like persistence).
