It is CSCvo11786 , fixed in a number of versions but none that I'm aware of being public yet. This was a real pain to identify but caught it on a whim.

We have an expect script that rolls though and emails us the socket counts for the SCCP Application process. You can do any number of things, reload the device, clear the sockets, restart SCCP application.

All of those things will disrupt the service for more or less time depending on which you choose, but when the socket count hits max it will simply stop operating anyways.

The VG204XM seems to open 1 socket (?) but the VG310/320 open one per each port that's configured, so depending on what's going on that may cause the application to disconnect, and how aggressive it retries, these can stack up quickly we found.
