The SPDY filter may send events to a child flow, after that child flow has been deleted. When a filter for the delete child flow processes this event, it may crash.
The tmm crashes.
The conditions that trigger this are unclear. The fix eliminates the behavior that caused a crash. The crash only occurs with a complex virtual server configuration and even then very rarely.
This issue has no workaround at this time.
The SPDY filter no longer sends events up on deleted child flows, thus preventing a possible crash.
