On rare occasions, a race condition may allow the wrong connection flow to handle Clustered Multiprocessing (CMP) responses. The CMP messages for flows that are quickly created and destroyed may match a flow that was already destroyed.
Traffic disrupted while tmm restarts.
This issue can occur on any device using CMP messaging.
