Hi!

I've just notices that about one in four of the new v9.90 tasks end up in
'Error while computing'!

Since yesterday my computers have processed 166 tasks and 42 of them
ended up in errors. I currently have four different computers running on this
project and none of them seems more affected than the others.

In the 'Stderr output' for the tasks I find one line particularly interesting:
...
terminate called after throwing an instance of 'std::filesystem::__cxx11::filesystem_error'
  what():  filesystem error: cannot copy: File exists [model-best.pt] [model-final.pt]
...

I've also processed hundreds of the v9.95 and v9.96 test-tasks and non of these
had errors.

Hope it can be fixed soon as it affects such a high percentage of the tasks.

Kindest regards,
Gunnar

Working on it. two issues have come up suddenly.. one is drastically larger memory usage, the other is the issue you see below. I've been updating discord since it was brought to my attention 12 hours ago. The memory issue related to OMP, but I thought the model-* issue was harmless and wouldn't be seen on volunteer machines. I'll be pushing out an update that fixes the latter, still not sure how to fix the former.
