I read
"pvget replaced caget, giving us two implementations that behave the same."
as both "caget" and "pvget -p
ca" were used with the same result.
Might point to a problem in the CA client lib as the common denominator.
Maybe one can attach gdb to the hung caget/pvget process and see why it's stuck and not exiting.
