Rarely LB::prime iRule with SIP filter can result in a tmm core due the flow control mechanism added in the SIP hudfilter and the fact that LB::prime, adds necessary count of prime messages in Q and calls mblb_connect synchronously which has the potential to traverse the entire serverside chain.
Rarely results in a core with LB::prime iRule. Traffic disrupted while tmm restarts.
LB::prime iRule with SIP filter is used.
