keyword=Locking cavity after EPICS reboot painful
The cavity would not lock after the EPICS reboot.
After another EPICS reboot I lost totally control of the laser and
rebooting EPICS would not help.
The empirical fix to the problem is to reboot the Compton computer and
then do an EPICS reboot.
I got control back of the laser after rebooting EPICS after the computer
One detail to know is the EPICS variable
COMPTON_LASERT_MIN has to be set to 35.8 instead of the default value 32.2
Not sure why we had to do that, the only thing I can see possible is the
Compton computer polling to much on the IOC for unknown reasons ( maybe
network sockets left opened ). To be investigated...
