Symptoms

TMM crashes when Application Acceleration Manager (AAM) attempts to handle stand-in on a cache writing failure

Impact

Traffic disrupted while tmm restarts.

Conditions

This occurs when stand-in is enabled on the policy, request queuing is turned on in the policy, the document changes at the backend, and writing to cache fails.

Workaround

Disable stand-in and/or request queuing.

Fix Information

TMM no longer crashes. When the newer document gets evicted due to cache writing errors, the stand-in document is used as configured.
