When using mirroring with a RAMcache virtual server, it is possible for flows to be left on the standby. Flows of this type consume memory, leading to an eventual out-of-memory situation.
Aborted flows consume memory, leading to an eventual out-of-memory situation in which tmm might crash. Immediate termination of flows on the standby system causes the flow to not be mirrored; if failover occurs, affected open connections on the active system result in immediate client aborts.
Using a mirrored virtual server with an acceleration policy (ramcache or WAM).
Remove the acceleration profile, or clear the 'mirrored' flag on the virtual server.
Mirrored flows with RAMcache no longer crash or leave zombie flows, so that tmm no longer crashes.
