Subject: CA communication problems

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
