What happens when you run the "camonitor" utility from EPICS base at the command line on that PV?  Perhaps the PV is really not changing like you think it should be.

Subject: Loosing half the monitor callbacks



Hi,

I would like to monitor a PV at 5 Hz.  Somehow I do get 5 callbacks every seconds
but only get the changes every the other time, like getting changes 1st, 3rd, 5th ...
two times, but never get changes 2nd, 4th, ...

Could you please enlighten me?

Thanks and best regards,
Dehong
