One of our PBXs dropped all of its calls and then proceeded to have a 10 second connection delay when answering, or trying to connect to an outside line. I've found the following errors in the logs, but cannot find a reference to them in any of the manuals. Would any of you know the meaning of these errors?

Thanks
