What is cufwPolAppConnNumHalfOpen?

This Gauge32 reports connections currently in the process of being established for the protocol/policy/target combination in cufwPolAppConnProtocol, cufwPolAppConnPolicy, and cufwPolAppConnPolicyTarget. It gives an admin a real-time view of in-progress setups specifically under one application policy-target pairing. A value that stays unusually high for a policy applied to a mail server target could flag delayed handshake completion under that application's inspection rules.
