>From studying the debugging logs, it looks like some channels
continuously report:
"write() pv not ready" when a client tries to write to them through the
gateway.
Then (usually triggered by a caget from a terminal) they become ready
"vcAdd() connecting -> ready"
After which a large backlog of writes are allowed through.

In some cases, I looks like a write to an input field is put on hold as
the channel isn't "ready" and then when a write to the Directive field
goes through, the input field becomes ready and the input is written
after the directive ... causing the "out of order", and thus failed,
commands.

What handshake between the ioc and the gateway is failing to set some
channels ready while others work properly?

Some help here would be greatly appreciated.
