This Counter64 counts connections that were abnormally terminated after they had already been successfully established, scoped to the protocol/policy/target combination in cufwPolConnProtocol, cufwPolConnPolicy, and cufwPolConnPolicyTarget. An admin can use it to find policies or targets whose connections keep dropping mid-session rather than failing to start, which points toward application or network issues specific to that pairing. A sudden increase for a policy governing a remote-office target, for example, would suggest something is disrupting already-open sessions to that office specifically.
