WP 13204 EDCU update and daqd restart

Per WP 13204 we added fw2 channels to the edc to save some frame writing information for the review of the new frame writer.

The usuall process was used:

1. regenerate the edc ini file

2. restart daq1 leg

3. restart the edc

4. restart daq0 leg

 

The daq1 leg was restarted around 8:20am localtime, followed by the edc.

The daq0 leg was restarted around 8:27am localtime.

There have been two restarts of h1daqfw0 since then, at 8:32 and 8:37.  Logs show that it was due to missing a input cycle (8:32) and running out of buffers in the circular buffer (8:37).  It as come back and appears to be stable now.
