FACT(s) (Environment):
Using stateless mode for AppServer.
All Supported Operating Systems
OpenEdge 10.2x
OpenEdge 10.1C
OpenEdge Server Technology Category: AppServer
CAUSE:
The client application is closing the TCP connection because it has exceed an idle connection timeout setting.
FIX:
Use the soReadTimeout parameter for the AppServer Internet Adapter to send a KeepAlive packet to the client application to prevent it from timing out when the AppServer is taking more time to complete the requested action than the client is configured to wait.
The default value for soReadSocket is 240 seconds if no value is specified.
The description of the parameter from the ubroker.properties.README file:
soReadTimeout=240
Specifies the amount of time, in seconds, the Aia adapter will wait for
a response from an AppServer before sending a "keepalive" message to
the client. The value of 0 specifies that the "keepalive" message is
not used. If the property is not specified, the default value (240)
will be assumed.
NOTE: After this value is changed, the AdminServer and the Java Servlet Engine should both be restarted.
