[…]… a simple method of reaching similar conclusion so THANK YOU!
You’re welcome.
Yes, I have seen other, some quite old, some quite convoluted, methods; replacing the log file, deleting the log file, trying to lock the log file etc.
And yes, the abovementiond method, in this case only used because somehow the Default debug level is running at full speed, does turn off debugging, so there will not be a log if something goes wrong. But in many cases it’s possible to replicate the problem, so one can run in debug mode if needed. ZoneAlarm saves a copy of the log file in a zip file; I don’t know the criteria for when it does this (size, age etc.). But if you stop & restart it should backup the old one and create a new one.
Since, in the above situation, the log activity was running amok 
one could watch the size change in real time, if one wanted. I have earlier mentioned a small tool that can monitor file size changes in real time, quite nifty. Monitoring file size changes in real-time.
