There is no access security on these IOCs.

I saw something very similar to this before, at the SNS, but I don't remember what I did to fix it.

Nadine will have to post seqChanShow for one of her problem PVs tomorrow, I think she's gone for the evening.

If you want us to help you're going to have to investigate and post some more information about those channels that are not receiving a first monitor (use seqChanShow to do that).  I can think of at least one reason why this might happen — your sequencer program user & host doesn't have Access Security permission on the IOC to read those channels for example, although if your IOC is not configured to use Access Security then that wouldn't apply.
