[09/20/2014 11:19:05] {lineout [current] rollover map for cool__man not found.
Could this have caused the error? It was around the same time...

Thank you for looking at this ticket :)

Hi, first I don't think it is related to the rollover map issue, but thanks for bringing that to my attention anyway.

It looks like your SQL server was somehow locked up, and each time OnTime tried to access the DB it got hung in a 'waiting' state, and eventually enough process threads ended up in that state that your sever eventually failed.

If the issue is not repeating itself, it will be very hard to impossible to figure out what happened this one time.

I will play around a little bit with my test system to see if I can create a similar situation, because I would have thought that the OnTime calls to the sever would just have returned a 'fail' code and moved on, and not been hung.

If you ever see this again, please let me know. If I find anything in my experiments I'll add a message to this ticket.

But my expectation is that I am not going to find anything useful and will eventually close this ticket, just because it is so hard to figure out a one time only failure that is not clearly the fault of OnTime.

BR, Edge
