Hi Eric,

(3) I point out my CSS is fine. Sometimes it can not see the PVs on the IOC that I can also not cainfo into, but a restart of the IOC fixes that, and CSS is fully functional to monitor and control all my PVs.
(4) My archive-engine is also fine. It tells me all my PVs are connected. If I call the IOC they disconnect of course, but restarting the IOCs brings back the connection.
(5) cainfo still does not see the PVs on 5064 port.
(6) My other client that does the ca_get() and ca_put() in C++ also has the problem of (4). This is the only reason I care about this. Cuz otherwise I have good functionality.
(7) If I kill my archive-engine and my CSS I have fewer entries from netstat, but the same behavior: 2 extra UDP connections reported for 5064, and I can not talk to those PVs with cainfo.

CS-Studio and probably your archive engine are Java applications.
The command line utilities are binaries (compiled from C/C++).

The configuration mechanisms between Java applications and C/C++ binaries are different. Unless you explicitly configure both the same way, it is expected that only changing the configuration for one type of applications will not affect the other.

Cheers,
