DAQ machines rebooted due to exceeding 208.5 day limit

WP8550

As a preventative maintenance item, I rebooted h1dc0 and h1broadcast0 at 14:00 PST. Both machines are running GT2.6.35 (which has an instability if running over 208.5 days) and both machines had been running for 211 days (last reboot Tue 30 July 2019). As expected an FSCK was forced by the OS, which slowed the reboot times to about 10 minutes. Due to the unusual restart sequence the DAQ came back partially, and then reset itself.

I completed my script to restart all the FOM displays which are NDS clients, needed after every DAQ restart.
