Subject: CA beacon routing problem
From: Evgeniy Tikhomolov <[email protected]>

We were happily running EPICS release 3.14.6 for more than one year on our system with mv162.

Suddenly ...

Actually, not so suddenly the network mask for TRIUMF site had been changed from 255.255.0.0 to 255.255.224.0.
We also changed the network mask on IOC and our Solaris servers.
And after that, suddenly we began to get on our IOC console the following error message:


../online_notify.c: CA beacon routing (connect to "142.90.127.255:9011") error was "S_errno_ECONNREFUSED"

After some time the connection between IOC and dm-screens is lost. If we set netmask to previous 255.255.0.0. in error message 127 is replaced by 255.

Can somebody explain the reasons for appearance of such error message?

Temporary we solved the problem by placing IOC behind firewall. In this case the error message dissappears and everything is like in old good days.

Thanks,
Evgeniy
