Recently the VisualCron service (7.6.1) crashed. In the process of restarting it, I keeps getting the following error. The only solution so far is to restart the Server.
Thanks.

Thanks for the feedback - we will try to reproduce this. Could you send log_serverDATE.txt to support@visualcron.com and tell us which time the service crashed approximately?

I have experienced this as well after upgrading to 7.61.

If I attempted to view the server log with debugging turned on it would crash the server service and I could not restart the server service without restarting the server itself. Since i disabled debugging I don't get the crash.

Here are the requested files from the specific server. Once I restarted it twice, the issue seems to have gone away. But I had noticed it periodically happening over the last few days.

Around 8AM in the log file it seems like it was restarted many times. Did you restart it manually or? Do you have any errors in the event log at that time?

I restarted it in an attempt to get it running. At the end I finally restarted the server. Also on those servers we have a scheduled windows task using powershell that will check every 5 minutes to see if the VisualCron Service is running and if not, it will start it again.
