Hi Oleg,

 

You should be aware that this version of CAS is under the control and dominion of Osprey DCS.

 

Personally, its complicated and inefficient to provide support for that version. This is due to the current review process, and the delays involved in getting any patches that I have attempted in the past approved.

 

Regrettably,

 

Jeff

Hi Jeffrey,

yesterday EPICS PVs updates stalled on one of our IOCs. IOC reboot solve the problem.
I am posting log messages from IOC console below. EPICS version is 3.15.5.

Should some corrections to the CAS be made, so that erroneous request does not cause suspended threads?

Oleg
