When resources are low, the TMM might crash when generating the cookie on the server side if there is no expected internal persistence data present.


Traffic disrupted while tmm restarts.


In low resource situations, the client side might fail to record persistence data. Thus the persist struct pointer is NULL. On the server side, an ASSERT triggers on that NULL pointer.



Fix Information

A potential TMM crash in low-resource situations with persistence cookies no longer occurs.
