Experimental Physics and
Industrial Control System

Hi everybody,

in one of our many-PVs IOCs we’ve received the error below. The IOC is still up and running and as far as we can tell there’s no functionality degradation. But since the error says to post to tech-talk, I figured I would ask anyway. Has anybody seen this error before? It seems to be on CA client side inside IOC so hopefully the client was able to spawn and use a new thread.

IOC is scheduled for reboot next Tuesday to recover the suspended thread, but we can leave it running a bit longer to gather some info if needed.
