wrapper.jvm_exit.timeout

Number of seconds to allow between the time that the JVM reports that it is stopped and the time that the JVM process actually terminates. 0 means never time out. Defaults to 15 seconds.

In normal operation, the Java side of the Wrapper will execute System.exit when it has completed its JVM shutdown cycle and is ready to exit. When this timeout is triggered, a message like the following will be logged.

    wrapper  | Shutdown failed: Timed out waiting for the JVM to terminate.
    wrapper  | Java Virtual Machine did not exit on request, terminated

If the application has registered its own shutdown hook which takes some time to complete, you could experience timeouts waiting for the JVM process to terminate. To avoid this problem, it may be necessary to extend the timeout to give the application's shutdown hook time to execute to completion. Be aware that as a rule, shutdown hooks should always complete almost instantly.

Example:

    wrapper.jvm_exit.timeout=5

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 as the JVM process terminates will be disabled.
