Subject: daqd fw dead 

For some reason, the daqd_fw service was dead on FB. This meant that no frames were being written since Aug 23, which probably coincides with when the c1lsc frontend crashed. Sad 😢 😭 🙁 . Simply restarting the fw service does not work, it crashes again after ~20 seconds. The problem may have to do with the indeterminate state of the c1lsc expansion chassis. However, this is not something that can immediately be fixed, as Chub is still working on the wiring there. So in summary, no frame data will be available until we fix this problem (it is still unclear what exactly the problem is). Team WFS can still work by getting online data.

Why were the CDS overview DC indicators not red???


Unrelated to this work: I had to key the c1psl crate to get the IMC autolocker functioning again. However, I found that the key 🔑 turns continuously - as opposed to having two well defined states, ON and OFF. Be careful while handling this.
