Just noticed that error in my cubeSQLAdmin log. Never saw it before or after. It seems associated with an attempt to access a particular database on that server. My web app's own logs show no error at all, and show the user accessing that database one second after the time logged by cubeSQLAdmin for that error, with the user doing database operations that are expected and successful. I have no errors file in this web app's folder.
What does that error mean? I also sent a message to Marco (cubeSQL's developer) yesterday.
