Symptoms

TMM may crash when using SPDY with iClient over iSession. System logs a message similar to the following: notice panic: ../modules/hudfilter/spdy/spdy.c:4108: Assertion "spdy pcb initialized" failed.

Impact

TMM crash. Traffic disrupted while tmm restarts.

Conditions

Connections are abandoned by external client. These connections might be suffering from connection closing in mid-conversation.

Workaround

Remove SPDY.

Fix Information

The system now handles this condition, so the tmm crash no longer occurs.
