Hello,
I have some problems of communication between an IOC and a client, both
running on different machines on the same subnetwork on a similar
environment (Epics v 13.4.7 under linux redhat 9.0 kernel 2.4.20-8).
At the beginning of the startup of the IOC, process variable values can
be got without problems from a client (either a simple command line or a
php script), but after a while, the data is not available any more and
the following message shows up on the IOC side :
CAS: request from 192.168.101.21:55894 => "bad resource ID"

CAS: Request from 192.168.101.21:55894 => cmmd=12 cid=0xffffffff type=0
count=0 postsize=0

CAS: Request from 192.168.101.21:55894 => available=0x1 N=0
paddr=(nil)

CAS: forcing disconnect from 192.168.101.21:55894
Would someone have an idea of what's going on ?
Thanks for your help
Christophe
