[cisco-voip] SDLLinkOutOfService

With this error sometimes we get "server is down" and also a loss of
phones, so this loss of communications is not just between call
managers? But with the phones also? One time the phones stayed
registered with the remote call manager until the ones on site were
rebooted.

Loss of connectivity, dropped tcp acks leading to the session being  
reset by one party, etc.  The only conclusive way to see what is  
happening is to get it in a packet capture and that can be difficult  
with a random failure.

Is there a typical network issue that may be causing this?
All the services show running and running since last reboot of call
managers.

In the alarm it will call out the remote node and application id.
Basically when this error is logged the tcp connection on port 8002
between servers running the ccm service has been lost.  The server
will automatically try and reconnect.

You've either got a transient network issue or a ccm service stopping/
crashing somewhere.

Chris,

    Yes all servers were moved, 2 to the new data center and one to an
offsite center.

IP's remained the same.

Melvin,

This means that either CCM or CTI is not able to communicate with CCM
or CTI on another node. How many nodes in the cluster? When you moved
the datacenter, were all servers moved? Were any removed from the
cluster? Did the IP addressing scheme remain the same?

Since we moved our data center we have been getting the alert
"SDLLinkOutOfService"
When I look at the call manager is up (or back up), sometimes we also
get an alert that the server is down (call manager).  We are running
UCM 6.1.2 1000-13 and are set to auto/auto.  Any ideas as to what may
be causing this?  Thanks for any help from anyone!
