I'm having an issue I've never had before. I don't get any task anymore (in these last days, it used to send me just 4-6 tasks per scheduler request, then dropped at zero). Is anyone else experiencing this issue?

This is an example of what happens.

This computer is set to only accept NVIDIA tasks, and it worked fine until these late days. I have already tried to reset the project from command line, but it didn't work. This computer is also set to accept 3 days of work. What's going on here?

I investigated this issue and found out that there was a 1 GB of free disk space minimum in preferences. After I had freed up some memory, it has started getting 4 tasks per scheduler request (not very happy for this low number, however). It seems no warning for exhausted disk space was reported by BOINC.

Anyone having such an issue might want to check whether or not all preferences are satisfied, even when no warnings are reported by BOINC.

This issue seems to have been solved.
