Hi Silas,
Usually those weird DRU errors are resolved by simply restarting topspin.
In this case, looks like yours took a bit more work.
The errors you're seeing after the reboot of the console are standard errors you
see after a console reboot. After rebooting make sure to restar=
t topspin and then before you try to run any experiments, run edprobe to re-identify
the probe, and then open a dataset and run ii a couple of times. The first
time will show those errors but the second time they should clear.
Cheers,Mike

We are using a bruker 500 MHz ultrashield, with a Avance III HD console using
topspin 3.5pl7 with a BBO probe.
A quick summary,a user tuned for 19F and forgot to tune back to 1H when done.
We tried to tune the 1H channel with atma on the sample it was having trouble finding
the valley. We stopped the atma and changed it to an ethyl benzene sample. then
we tried to atma 1H again and while this worked better we could see the valley
but after about 5+ minutes we got the message
"Exception in DRUContr 1: acqTransSendEvent: Almost Out of Message Buffers -> Experiment aborted by DRU1"
then some ipsoControl errors.I tried to restart the PC and topspin and that did not resolve the issue.
I then did a console reset and it seemed to work, but when I ran a topshim the
message
"Error in master: error 13 in AQS1" -- slot 1 rack 1 power failed" then "error in ipsoControl:: checkStatus(): status line active"
There were several other error messages that I attached on the below PDF.
Any advice you can give. --
