The symptom is that when we run a scan, nothing happens - no error, no data saved to the datavault, the session just appears to be running the scan method indefinitely. We think it's a problem with the qubit server because when we restart it, scans seem to work again. I haven't seen this behavior on any other computers yet.

I think it should get cleared\neach time you re-initialize at the beginning of an experiment, but I\nsuppose there might be a leak in there.\n\nAlso, this wouldn't really explain it because as far as the sequencer is\nconcerned there's no difference between the first run of a new dataset and\nrun n+1 where you just increment the delay time (for example). Uh, right?\n\nOn Tue, Jan 26, 2016 at 10:52 PM, Daniel Sank <notifications@github.com>\nwrote:\n\n> That's interesting. @maffoo <https://github.com/maffoo> does the qubit\n> sequencer cache data related to each run's configuration?
