This is my third time to crash a real-time machine. This time I crashed c1lsc.
I physically rebooted c1lsc machine by pushing the power button and it came back and now running fine.
(what I did)
The story is almost the same as the last two times (1st time, 2nd time).
I edited c1lsc.ini file using daqconfig and then shutdown daqd running fb.
Some indicators for c1lsc on the C1_FE_STATUS screen became red. So I hit the 'DAQ reload' button on the C1LSC_GDS_TP screen.
Then c1lsc died and didn't respond to ping.
