Hello all –
I am trying to set up something to do some automated testing of communication with a running IOC with PyEpics, but unfortunately I am running into some inconsistent behavior which makes it difficult
to use as a reliable testing mechanism.
Specifically, if I have an IOC (EPICS base 7.0.3.1) up and running on the same machine, and run the following script:
from epics import PV
pv = PV(“test”)
assert pv.connect()
then most of the time, this works exactly as intended. However, somewhere around 1 in 5 times or so, it fails. I have tried to look at the network traffic (using Wireshark) between the IOC and
the python client, but unfortunately I don’t see a difference between successful and unsuccessful connection attempts.
I am running both IOC and client inside a linux VM on my mac.
Any help would be appreciated,
Cheers,
Simon
