I have a problem where I will open EG, run my process and let EG idle after completion for a bit (the project takes a while and I work on other things until I'm ready to return).
However, when this happens and I let EG idle for ~10 minutes, the next action raises an error and EG stops working. The only way to resolve this is to restart EG.
"SDS Failed to provide the SAS workspace"
I look in the log and I see that that the connection to the workspace server fails the "IsWorkspace Alive()" test fails.
In the logs I see:
2019-03-08 13:59:47,920 [35] ERROR SAS.EC.Directory.Model.Server [(null)] - IsWorkspaceAlive() - Test failed
.
. <trying authentication>
.
2019-03-08 13:59:47,926 [36] ERROR SAS.EC.Directory.Model.Server [(null)] - Connection failed to <host:port>
When i look in the Object Spawner logs, I see the credentials are accepted and a connection returned.
2019-03-08T14:24:39,862 INFO [00882728] :<user>- New client connection (76694) accepted from server port 8591 for user <user>. Encryption level is Credentials using encryption algorithm SASProprietary. Peer IP address and port are [::ffff:<client ip>]:<seemingly random port> for APPNAME=SAS Enterprise Guide.
Does anyone know why this would be happening or where I should look next?
It's possible a network firewall is the cause: http://support.sas.com/kb/47825
90% it's a firewall or other part of the network infrastructure that drops connection.
