The Tomcat Java option parameter JINTEGRA_OUTGOING_CONNECTION_TIMEOUT is used to set a timeout on the PDUManagerImpl Threads. This is useful to define the time a COM connection from WebOffice to the ArcGIS Server is held. This way, it is assured, that that no time-intensive ArcObjects calls run into a timeout. Uncontrolled growth of ArcObjects threads is avoided.
Note: The timeout setting is global. If one map service configuration to be used in WebOffice, has a higher timeout (default = 600000ms --> 10 minutes), you will have to increase this value.
The Java option parameter is implemented for ArcGIS Server with the String:
-DARCGIS_OUTGOING_CONNECTION_TIMEOUT=<time in ms>
