Is a caRepeater bug was introduced starting from Epics
3.14.12?
It is intermittent, and may occur when "Related Display"
button on an medm screen is pressed.
We were able to reproduce "Virtual circuit disconnect"
message (see below) with Epics 3.14.12, Epics 3.14.12.1, and Epics 3.14.12.2 but
not with Epics 3.14.11.
Other observations:
1) Workstations with Epics 3.14.11 do not experience such
"Virtual circuit disconnect" problem with the same IOC, so this bug is likely on
a client side.
2) MEDM build with Epics 3.14.12.2 does not experience such
"Virtual circuit disconnect" problem while running on a workstation with Epics
3.14.11 installed.
Is this bug in the caRepeater code?
Any suggestions?
