OMC and DAQ restarts

Dan, Jim, Dave

Two OMC model changes were made. Both required a DAQ restart.

The first DAQ restart proceeded normally, the second did not complete. h1dc0 reported a bad master file in its log files. In fact it appears that around this time h1dc0 attempted to start three times, each time creating a running configuration with either missing or corrupted master files.

We logged into h1dc0 as root and restarted the daqd process manually. This time the master file was read correctly and the DAQ restarted normally. We are unsure of the original problem, possibly an NFS issue between h1dc0 and h1boot?

Note that on both DAQ startups today, the broadcaster was the last to start. Normally it is the first to start.
