Re: Trying to know why tomcat shuts down
Is Tomcat getting killed by the OOM Killer? http://linux-mm.org/OOM_Killer On Feb 20, 2008 8:12 AM, David Delbecq [EMAIL PROTECTED] wrote: Hello, our tomcat, in a test environment, is shutting down unexpectedly. There is no messages about stopping webapp, or even receiving SHUTDOWN message from management port. It's just normal webapp behaviour in logs and that's all. We notice this when someone comes in and says reserver does not respond, whe check processes (a linux 32bits box), and no track of the jvm. No specific operation seems to trigger it. The jvm is not dying, cause that would have led to the presence of a pid.log file and messages in catalina.out. It's not the webapp calling System.exit, because tomcat runs with a security manager that forbids system.exit from webapps. We have no clue on how to get reason of this shutdown. I have attached now a shutdown hook that will call an external script that itself will ask jvm for a dumpstack (kill -3), in the hope we get some information. But our tries with regular shutdown seems to point that jvm ignore such request when it's processing the shutdown hooks. Any suggestion on tracking this greatly appreciated. -- http://www.devlog.be (a belgian developer's logs) - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Trying to know why tomcat shuts down
Everyday, learning something new, today is check linux system logs if your tomcat disappear [30575826.592000] Out of Memory: Killed process 734 (java) Thanks for your help, you got it right. That server might need a bit of additional memory ^^ En l'instant précis du 20/02/08 14:29, Peter Crowther s'exprimait en ces termes: From: David Delbecq [mailto:[EMAIL PROTECTED] our tomcat, in a test environment, is shutting down unexpectedly.
