Subject: Frozen? 

[Jenne, Q, Diego]

I don't know why, but everything in EPICS-land froze for a few minutes just now.  It happened yesterday that I saw, but I was bad and didn't elog it.

Anyhow, the arms stayed locked (on IR) for the whole time it was frozen, so the fast things must have still been working.  We didn't see anything funny going on on the frame builder, although that shouldn't have much to do with the EPICS service.  The seismic rainbow on the wall went to zeros during the freeze, although the MC and PSL strip charts are still fine. 

After a few minutes, while we were still trying to think of things to check, things went back to normal.  We're going to just keep locking for now....
