Add more info:
we are using sequencer v1.8.3 and EPICS 3.12.2 for the following
iocs at Jefferson Lab.

> 
> Here's a typical problem at Jefferson Lab (taken from log):
> 
>  The global sequence on iocin1 claimed the signals from iocin3 and iocwa4
>  were monitored but not connected even though the iocs were indeed up and
>  the signals reachable by caget.  iocin3 and iocwa4 also were not providing
>  signals to iocin1.  The solution was to reboot iocin1 to force the se-
>  quence to re-establish connections to various viewer iocs. Rebooting the
>  data source (iocin3 or iocwa4) did not fix the problem.
> 
> Anyone have any suggestions for how to find or fix this?
