Hello Maurizio:

As Jeff already replied, the Channel Access server on the IOC should not be affected by the specific order in which CA clients do things.
The issue may indeed be in the driver support for your VME hardware.
Still, if you want to narrow the issue down from the CSS side, try CSS versions 3.1.x (for SNS, you can find those older ones on https://ics-web.sns.ornl.gov/css/updates/apps/?C=M;O=D).
CSS 3.2 uses the PVManager, 3.1 doesn't, so that would allow you to compare the behavior with two different CA client implementations.

Thanks,
Kay
