Hi,
We are having very occasional issues with CA timeouts (with a timeout of 3 seconds) from our control software (GDA). I think it is because the IOC sometimes doesn't respond when it is overwhelmed with requests and when we have multiple instances of EDM
screens open it can produce a lot of requests. These timeouts can cause scans to fail, so responsiveness for the EDM screens is much less important. If we add an appropriate value for the CA Priority option to ca(get|put) in control software requests, would
that make the IOC respond to it in preference to other clients and stop the timeout errors? Or am I misunderstanding what this option does?
Cheers,
Gary
