About Tomcat configuration settings
Serializing the forms indicates persisting cache in memory to disk in a clean way. Because the time required to serialize forms can vary depending on their size and complexity, you might need to increase the Tomcat shutdown time and thread stack sizes to enable the efficient serialization of your forms.
Addressing the timeout setting
The cache objects are available from memory to disk across restart only if you have a clean Tomcat shutdown. In the Apache Tomcat properties, set the shutdown time and thread stack size to an appropriately high value. Refer to the following screenshots:
Here, Timeout = 0 indicates, wait for a clean shutdown and do not stop the service.
For example, if you are using the version of Tomcat that was bundled with your Windows BMC Remedy AR System installation, the service might fail to restart if the timeout setting is too low and you have cached many forms.
