We have a system running VSOM 4.2.1 with approx 160 cameras on it. Most are analog coming over from cisco encoders, and 3 panisonic ip cameras. System is a bit sluggish in general, but working properly. Today as I was teaching management how to use the system, we were having dificulty pulling out .cva files. It would pull out .avi files properly, but when trying to save even a minute of a single camera it would fail. It would appear to be saving, ask for a location/name, and come up with the status bars. Without them moving, it would go away, and nothing would be saved. I've checked known issues and bugs, but could not find anything. Any ideas on things I can check? It does this on all computers on the system, so I've ruled out a computer issue. It also had been working previously during testing. Log files appear to be clean.
Thanks in advance.
