- Create a backup of /etc/tomcat/server.xml
- In /etc/tomcat/server.xml look for the following string:
- Change the value for connectionTimeout to "600000"
- For SUSE Manager 4.1 it should look like :
<Connector URIEncoding="UTF-8" address="::1" connectionTimeout="600000" maxThreads="150" port="8009" protocol="AJP/1.3" redirectPort="8443" secretRequired="false"/>
Note: maxThreads may have a different value, depending on the configuration, this value should not be changed.
- Restart of the SUSE Manager server with: spacewalk-service restart
AJP is a TCP-based protocol for fast communication between apache and tomcat and is used at every HTTP request that involves the Java stack. There is an optional watchdog mechanism to kill AJP connections if they are inactive for too long. The JVM might not respond to such keepalive messages if it is too busy or during garbage collection pauses. The keepalive time may be configured via the keepAliveTimeout option found in /etc/tomcat/server.xml. For more information please see: https://tomcat.apache.org/tomcat-8.5-doc/config/http.html
