Subject: focus loop issue; Re: 2.5m obslog 20060917 (MJD 53996)
Regarding the focus loop problem, there were murmur messages from
sdssad1 starting at 17-Sep 17:00Z and ending when the astro crate was
rebooted at 18-Sep 03:55Z reporting that the focusTask on sdssad1 had died.
I'm guess that the watcher didn't have anything to say about these
messages, and that is why they were not noticed, so I updated PR7062
[Watcher needs to catch DA error messages].
