This is interesting. I am used to seeing Theory using only a small amount of memory. But this one is using almost 7 GB.
300.06 Theory Simulation (native_theory) Theory_2390-1101092-12_1 6751.79 MB i7-9700

NOTE: The CPU usage is only 12.50%, and it has errored out on one other machine. I will get rid of it in a few more hours.

I have 32 GB on that machine, and am glad to see it being used. Is this a new series of work?

Is this a new series of work?
if yes, will this be true for Windows VM tasks also?

It ended on its own. I did not have to abort it.
Obviously it was seriously wrong.

EDIT: I am not sure what happened. It is still shown as running.

EDIT: It is still shown as running. So I have aborted it.

Another one shows 760 MB, which is a little high but not spectacular yet (after 20 hours).

And its CPU usage is OK at 99%, so I would hope that it will complete.

Looks like it has been the same event generator (madgraph5amc) that caused the trouble here:

OK, I don't know how that affects the science for this one, so I will just let it run up to maybe 4 days.
The size is up to 865 MB now.
