10.3 and 3.1 Errors (5465), (5476) Tomcat Connection Timing Out
Problem
Tomcat disconnects every 30 minutes if not used. We see errors 5465 and 5476 for each connected database in the broker log. The AppServer is configured with minSrvrInstance equal to maxSrvrInstance and this does not influence the sessions closing or not closing.
Shutdown request received. (5465)
Shutdown. (5476)
Solution
Tomcat, and other command Java Servlet Engines (JSE), usually have configurable idle sensitivity settings and timeouts.
It will be necessary to adjust the timeouts to ensure that the JSE does not close what it considers an idle connection.
For Tomcat, the document discussing timeouts can be found here:
http://tomcat.apache.org/connectors-doc/generic_howto/timeouts.html
For other JSE providers please contact the JSE provider to inquire how to configure timeouts.
One customer specifically adjusted the Tomcat session-timeout setting found in the /conf/web.conf file to adjust session duration.
