I'm remote-operating my 3706 with a 3721-ST card and perform 4-Wire measurements.
I use the LabView-driver and have a problem with the "scan.execute" visa write in the belonging vi.
Using the foreground-scan I send my configuration including scan list/count, then it sends an error (-1073807305) while the keithley is still measuring which of course messes up the rest of my program.
I fixed it with making a short Test-Scan (some sekonds) and then I calculate the time needed for lets say 100 measurements and add a delay between the visa write and the error-query. Is there a better way to do it?
Since some time I noticed the error "No comm link" in the display which occures sometimes after 2h, sometimes after 16h of operation.
A restart fixes it, but it is kind of unpredictible. Do I have to expect this to get worse?
Thank you already,

That no com link error is intermittent at best. And that is probable causing the errors.
I would recommend sending the unit in for service when you get a break from using the unit.
They should be able to put it through its paces and discover this issue.
The service number is 5030-627-2445.
