The TMM crashes while resuming from a HTTP_PROXY_REQUEST event.
Traffic disrupted while tmm restarts.
A HTTP_PROXY_REQUEST iRule event parks. Pipelined ingress occurs.
Don't use parking iRule commands within the HTTP_PROXY_REQUEST event. If a parking command must be used, the following may work: Try using TCP::collect to disable ingress while a potentially parking iRule command executes. TCP::release can be used after the command completes to restore normal behavior. Another work-around is to set max-requests to 1. (Disabling pipelining.)
