The coordinates shown in the message are
Global Coordinates which can be resolved into a sim name and coordinates that you are familiar with (e.g. Ahern(12, 152) 78m up. However I think such would be a waste of effort.
Having recently spent some time digging through logs, they are filled with garbage information about all sorts of conditions that shouldn't appear but do. For a firm that was actively attempting to debug their platform instead of trying to rake cash out of it while they do something else, they might matter. That likely doesn't apply here.
Just for kicks, here are some of the more entertaining ones I ran across in one log from a typical "working just fine" session:
