If a GAB port was closed and reopened before LLT state cleanup action is completed, then GAB logs a message similar to the following:

GAB INFO V-15-1-20102 Port v: delayed reopen

Recommended Action: If this issue occurs during a GAB reconfiguration, and does not recur, the issue is benign. If the issue persists, collect commslog from each node, and contact Veritas support.
