Thanks everyone for your helpful explanations and comments. We'll give
the CA gateway with base 3.14.11 a try, but it is nice to understand why
its working this way.

Hi Dennis,
I had similar problems with the motor record. Build the latest version
of ca gateway with base 3.14.11 or higher and the problem should be
fixed.
Starting from 3.14.11, the portable ca server, which is used in the
gateway, is able to distinguish between put and put-callback requests.
Before, the gateway always did put-callbacks, even if the client (e.g.
medm) didn't. However, the motor record, the busy record and some
other record types from synApps related to long-term actions (i.e.
scans) don't sent the callback until the action they perform has
finished (not when the action has successfully started as all the
other records do). That blocked the gateway.

We've encountered an odd behavior the last couple days that has us
pretty confused.

Can someone please explain this and/or suggest a fix?

When I set a certain PV going through an EPICS gateway, the setting
doesn't "work*" entirely.

If set through a non-gateway-ed connection, everything works fine.
