Subject: Receiving duplicate monitor values using CA PV Gateway

Hey all,

We are seeing duplicate values when first creating our subscriptions through the CA Gateway. Is this normal? If not, does anyone know what might be causing it?

Note: We are on EPICS V3.14.12.8 and Gateway 2.1.0

We see this in our applications and in tools such as camonitor. Here is an example output from camonitor, for a heartbeat PV updating every second:

$ camonitor IOC1_HEARTBEAT
IOC1_HEARTBEAT               2019-05-29 20:19:51.038659 7651
IOC1_HEARTBEAT               2019-05-29 20:19:51.038659 7651
IOC1_HEARTBEAT               2019-05-29 20:19:52.038654 7652
IOC1_HEARTBEAT               2019-05-29 20:19:53.038657 7653
^C

Thanks,
William 'Casey' Layne
