Subject: Report - FEE Kernel Panics (Update on 48) 

Update on issue #48 - the "confusing state" is that the FEE has restarted and hence is undefined again.

An attached TTY log from the pi shows that the module is kernel panicking.
I have seen a couple of FEEs panic with the same error now.

(NB. The Day/time of the logs is wrong as the pi does not have the correct time - pis dont have a RTC or Internet access so the time isn't corrected)

Temperature of the modules is fine.

Aida is currently powered off (and I am away from GSI)

Quote:

it seems a FEE somtimes enters a confusing state and stops sending data
the current merger requires all FEEs to be active and so this stops the entire system from proceeding.

On MIDAS the page reports the module is "undefined"

On the TTY console (PUTTY) it returns: do_GetState returned z=0 and 8

Resetting the DAQ in question via MIDAS works (Putty logs of the stages shown) and then the merger resumes without trouble.
