We left an experiment running over night and aren’t sure why it stopped. It looks like errors starting appearing soon after launch even though the lab tech reported it failing sometime later. Can someone please help figure out what’s going on? Let me know what additional info you need. Thank you.

Hello, what operating system version are you using? Has it been updated to the latest variant from the Chi.Bio website?
I have observed an error somewhat similar to this in the past but updated the OS in order to try to cover it off. If you are still seeing it that is worrying as it means something might still be amiss…

Thank you very much for the reply. We did load the latest OS available before starting experiments, but I’ll have to check the version number as I’m unsure. I’ll go ahead and load the latest version available on the Chi.Bio website and see if we still get the errors. I’ll be in touch either way. Thanks again.

Great, let me know.
Also, by OS I mean the underlying Beaglebone operating system (i.e. Debian Linux), not just the Chi.Bio software on Github. The underlying OS is the one causing these faults, we have been trying to patch it…
