While double-checking your suggestions I found that one of the channels that was being monitored came from another vxWorks IOC (mistake on my part).  Surprise, surprise...it never has any disconnect issues.  Following that lead, I found that the problems seem to be centered around a dynamically assigned pv in one of my two sequencers.  When I hard-coded that pv assignment the problems went away.  This remains consistent.  What's confusing me a bit is that I use dynamic assignment in the working sequencer, I just don't do any reassignments.

Hi, Wesley.

There have been a number of bug fixes related to pvAssign.  You
can find these in the release notes (just search in the page for
"pvAssign"):

What version of the sequencer are you using?
