This problem is similar to
https://epics.anl.gov/tech-talk/2020/msg01951.php, but not the same.
I have an archiver appliance which has been happily running on a Alma
Linux server for several months. We had a
maintenance shutdown which turned off the IOC servers, but the archiver
remained active. When the system
came back up again, ~150 PVs, which I verified as alive and active,
would not reconnect, whereas thousands more
did reconnect as usual. Any ideas?
What you could try:
Start an IOC (loading a single record with an arbitrary nonexisting name is enough) in the network that the archiver is in or listens to. (Depends on the exact configuration of your engine.)
That will create a Channel Access beacon signal "new IOC coming up" that any client library may see as a hint to try reconnecting disconnected channels. Note that the caRepeater is needed to be running on the client (archiver) machine for this to work.
Start/stop that extra IOC a few times. (Even if it doesn't help, it will hardly have any side effects.)
Cheers,
