I run discovery once a week on a Saturday and periodically it fails. It used to be that I could re-run Discovery on all of the subnets and work out which one was causing the issue but now they all seem to run through successfully when I run them manually. Is there a way that I can see which subnet or device is causing them to fail?

I am running 2.0.1.222 on an R620 with 2x 2.9GHz 8 Core Xeons and 32GB of RAM
