Problem Note 62319: Connections might become disconnected and return "ERROR: Conversations terminated..." when you use SAS/CONNECT® software
 |  |  |  |  |
When a SIGNON command has been successfully executed to connect to a remote server, the connection might become disconnected and return the following errors:
ERROR: A link must be established by executing the Signon command before you can communicate with the remote host.
This issue occurs due to network inactivity caused by complex code processing on the remote server. An internal firewall setting might detect this period of inactivity and terminate the connection.
Click the Hot Fix tab in this note to access the hot fix for this issue.
IMPORTANT: The hot fix needs to be applied to both the local host and also the remote host.
After you install the hot fix, you can set the CONNECTKEEPALIVE environment variable in the CONNECT server session. The CONNECTKEEPALIVE environment variable must be set at invocation of the CONNECT server. You can put it in a CONFIG file or in the CONNECT server's launch command. For example, the following code sends a keepalive packet from a thread started by the CONNECT server session every n seconds:
Setting this environment variable prevents firewalls from shutting down the connection between the CONNECT client and server when there are long periods of inactivity on the connection.
