Please provide some additional details about your environment:

What OS is the Metadata Server running
Are there any firewalls between this client and the server(s)?
How long has this issue been occurring?
Is this a new issue or has this issue happened ever since the environment was created?

The first thing I'd check is a network or host-based firewall. If there is a firewall, there is a keepalive parameter you can set.

@MG18: I don't see that the KEEPALIVE param was available in SAS 9.3. Perhaps another contributor can comment or you can also open a track with SAS Tech Support.

My suspicion remains the firewall. In my experience, the network security teams will make updates to firewall parameters from time to time without informing the user communities. I suggest you ask your firewall team if they have modified the idle timeout or any other settings that would apply to your communications. Often times these are global settings for the entire firewall policy and not specific to your set of rules.

Hope that helps!
