CA Unified Infrastructure Management
analyzing some intermittent connection problems between hubs tunneling we've found many connections in CLOSE_WAIT on our UIM Server (about 25000).
We've 1 hub tunnel server connected to 24 hub tunnel client
All nas probes located in tunnel client replicate alarms in one direction to nas probe located to tunnel server
All Infrastructure Managers are connected to hub tunnel server
Analyzing CLOSE_WAIT connections we find that they are all assigned to NAS probe. Deactivating and activating again nas probe resolve the problem but after 2 days we've again many CLOSE_WAIT connections (about 14000).
