Can't get into SV8500

[phadobas]

As of this morning, I can't connect to my SV8500 via PCPro. I tried over IP and serial and in all attempts, I get the following error message:
"Command is being used at another terminal or you must reenter password".

I use PCPro almost daily. The system got upgraded to S7 about 4-5 weeks ago. I was using PCPro just yesterday, and left it logged on overnight. This morning, when I entered any command, I got the above message, so I logged out, and now I can't log back in. I keep getting the above message.

I'm aware of 2 separate computers running PCPro to connect to the system for programming, and I went to both and closed PCPro on both and re-opened and tried to log on, with the above message on both.

I could re-boot the system, but I have about a 1000 users on it pretty much 24/7 under normal circumstances, and right now we are using the system even more than usual. No phone service is affected currently.

MA4000 works as long as it doesn't have to get data from the SV8500 or doesn't need to write data to it. It times out when it needs to talk to the SV8500.

PC PRo Tools is now web-based and it works, but as I said, I really don't want to reboot the system. Anybody has any good ideas?

Resolved. I got in. I went to MA4000 and run a PBX backup as a background task. It completed successfully. I checked the logs on MA4000.
It said:

backup starting
PBX locked
backing up....
PBX unlocked
backup complete

After this, I was able to log in with PC Pro
