[Wrapper-user] Wrapper not respecting wrapper.restart.delay

I am using wrapper version 3.2.3 for an app running on Java Version: 1.6.0_04-b12 Java HotSpot(TM) Server VM on Redhat Enterprise 2.6.18-53.el5xen. I am having a problem I have seen in many other forums, which has the following signature: ERROR | wrapper | 2008/12/11 08:03:59 | JVM appears hung: Timed out waiting for signal from JVM. ERROR | wrapper | 2008/12/11 08:03:59 | JVM did not exit on request, terminated STATUS | wrapper | 2008/12/11 08:04:01 | JVM exited in response to signal SIGKILL (9). ERROR | wrapper | 2008/12/11 08:04:01 | Unable to start a JVM The explanation in the other cases is that there are resources which have not been freed up when the wrapper tries to restart. The fix suggested is to set the wrapper.restart.delay property to some value high enough for the resources to be freed again. I have set it to 30, but it doesn't seem to be taking effect. The output from my log above is from after having set the property and restarted the app with the wrapper. Below is the content of our wrapper.conf. Any suggestions would be appreciated!
