Thanks Ben.

I'll try 2.1.2 abd report back.  I'm also considering doing periodic pvGets.

[snip]

I don't think use of pvAssign has anything to do with the problem (but I could
be wrong). Whether safe mode helps depends on whether access to a 'float' value
might be non-atomic on the system (OS, arch) on which your IOC and SNL program
run. Thus I need more data before I can judge conclusively.

I have heard the same complaint form at least one other user: sometimes
(monitor) events that should happen simply don't. I cannot guarantee that the
latest release (2-1-2) does not contain this or a similar bug. But the
internal workings of the sequencer have been cleaned up quite a bit since the
2-0-x versions, so it may well be that simply switching to the new version
fixes the problem. In any case, if it does /not/ do that, I can guaranteed that
I will be highly motivated to find out the reason for this and fix it ASAP.

Cheers
Ben
