Experimental Physics and Industrial Control System
**** Has anybody else experienced these problems? ****
When we are operating sliders to write process variables through the CA
gateway, every now and then on releasing the sliders the gateway writes
huge (and I mean r e a l l y huge positive or negative) numbers to
the IOC, which set the PV to the upper or lower end of the allowed range.
This never happens if you don't use the gateway.
We observed this behaviour both with dm and with edm (running on Solaris
or Linux Redhat 9).
The gateway is running on a Linux (Redhat 9) box. Several gateway
releases up to Beta18 (built against EPICS R3.14.6) exhibit this behaviour.
We lost a couple of devices, where a user hadn't specified a proper DRVH
for the setpoint.
We have taken the gateway out of operation until this is resolved.
