Please test this on 3.6.3r3, and provide an error report of that occurrence.

Thanks, I'll look into it soon.

Comment by me4502

I believe I just fixed this.

Comment by paulj1x

Thanks! I've been running it the last four hours without an error, but the server has been lightly loaded, tomorrow will be the real test.

I am seeing something new:

The variable thing you can ignore, I've since fixed that.
