wrapper.shutdown.timeout

Number of seconds to allow between the time that the Wrapper asks the JVM to shutdown and the time that the JVM side of the Wrapper responds that it is stopping. 0 means never time out. Defaults to 30 seconds.

If you are experiencing timeout problems as your application is shutting down, you may want to consider extending this timeout. This can happen in cases where the shutdown code within the application takes a long time to complete. As a test, try setting this property to something like 300 (5 minutes) and see if this makes the problem go away.

If the application still times out quicker than the 5 minute test timeout, then the problem may be in a later phase of shutdown. Take a look at the wrapper.jvm_exit.timeout property.

If the application still times out after waiting the full 5 minutes then you will have to do some debugging of your application to see what is taking so long. If it is possible to speed up the application's shutdown phase, that would be best. Otherwise set the timeout to a value that allows the application to shutdown cleanly.

It is best to choose a value which is long enough to let the application run reliably, but short enough that the Wrapper will react as quickly as possible in the event of an actual JVM hang.

If the shutdown procedure sometimes takes a long time. One alternative to setting a long timeout is to periodically call the `WrapperManager.signalStopping(n)` method. This method gives the application the ability to request more time to shutdown, while at the same time assuring the Wrapper that the JVM is alive and well.

Example:

    wrapper.shutdown.timeout=30

WARNING |  | While the ability is there. Be aware that setting this property to 0 or some large value will mean that the Wrapper's ability to detect a JVM hang during the shutdown phase will be disabled.
