4) Why does CSS delete the monitor before issuing a put?

That is an interesting question...

Not sure what that means. Who saw that happening where?

Me observing with wireshark.

With CSS "Probe"

Both Probe and BOY.

or ..? Talking to an older IOC or one that supports DBE_PROPERTY? Using a
gateway or not?

The IOC (and gateway) were build against Base 3.14.11. Direct

connection to the IOC works. From my memory, the CA gateway was not

forwarding the monitor create request at all, so the IOC version makes

no difference in this case.

...
So by default we disabled the DBE_PROPERTY support. It's a CSS preference
setting.

Unfortunately we seem to have a css distribution version (css-nsls2

3.1.2) where this defaults to enabled and can't be disabled :(

I suspect we will pick up the improved behavior you describe in our next

upgrade.
