Subject: notification of discard of subscription updates

Hi,

In the channel access reference manual, under 'Server Subscription Update Queuing', it states:

"There is currently no message on the IOC's console when a particular client is slow on the uptake. A message of this type used to exist many years ago, but it was a source of confusion (and what we will call message noise) so it was removed.

There is unfortunately no field in the protocol allowing the server to indicate that an intervening subscription update was discarded. We should probably add that capability in a future version. Such a feature would, for example, be beneficial when tuning an archiver installation."

I was wondering if this is still something being considered? If I wanted to modify the source to enable it, would it be very difficult to do so? If not would someone be willing to point me in the right direction?

Thank you for your time,
Patrick
