Let me try to explain. In your initial report you quote two stack straces. Both of these start at org.apache.catalina.startup.Catalina$CatalinaShutdownHook.run This is a shutdown hook that is registered with the JVM at tomcat startup. When JVM shuts down (System.exit(), CTRL-C on windows, catalina stop etc) this shutdown hook is executed. The exceptions you are seeing are as a result of this shutdown code. My point is that something is causing the JVM to shutdown. As part of the shutdown process the JVM calls the shutdown hook. During the running of the shutdown hook some exceptions occur and this is what you are seeing. The hard part here is trying to work out what is causing the JVM to exit in the first place. I have previously checked every call in the tomcat code to System.exit() and they are all preceeded by a log message. On this basis I think you can rule out any tomcat code. Is there a System.exit() in one of your webapps? Something that might be worth trying is running under a security manager that would thow a security exception if a webapp tried something like this. It is also possible that the OS is signalling the JVM to shutdown. Tracking this down could be trickier. If you wish to discuss this further please use the tomcat-user mailing list as it is more appropriate to this type of discussion. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
