Tomcat Crush
Hello all, I am running tomcat 4.0.4 on solaris8. I get a very strange problem where with no specific reason tomcat produces the following error In the Catalina_log: 2003-04-01 19:12:54 Ajp13Processor[8009][9] process: invoke java.net.SocketException: Socket closed at java.net.SocketOutputStream.socketWrite0(Native Method) at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92) at java.net.SocketOutputStream.write(SocketOutputStream.java:126) at org.apache.ajp.Ajp13.send(Ajp13.java:525) at org.apache.ajp.RequestHandler.finish(RequestHandler.java:495) at org.apache.ajp.Ajp13.finish(Ajp13.java:395) at org.apache.ajp.tomcat4.Ajp13Response.finishResponse(Ajp13Response.java:1 96) at org.apache.ajp.tomcat4.Ajp13Processor.process(Ajp13Processor.java:464) at org.apache.ajp.tomcat4.Ajp13Processor.run(Ajp13Processor.java:551) at java.lang.Thread.run(Thread.java:536) This continues for sometime. The system has about 300 concurrent users at any given time. The after about 8 hours tomcat will crush. Any ideas what might be causing this. Thanks in advance, Greg

Howdy, There's always a specific reason ;) It's hardly ever obvious, unfortunately. In this case, could it be because the client closes the browser or goes to another web page while the request to your site is processing?

RE: Tomcat Crush
I don't think so. I have monitored the Catalina_log while stopping the request of completely closing the window but the exception did not appear. If it is that is there anything I can do to prevent tomcat from crushing? Could it be something else?

RE: Tomcat Crush
Howdy, As you can see from the stack trace, the exception is from the AJP connector, not from tomcat internally. I also wouldn't qualify this as a tomcat crash (and certainly not as a crush ;)) because the JVM doesn't stop and the server responds to further requests. Until you can reliably reproduce this, you're not likely to be able to stop it...

RE: Tomcat Crush
I agree with all this but the end result is that for some reason the Tomcat process dies after a certain amount of time that these exceptions happen. Give that as you say it looks like the connector is causing this what can I do to stop it from happening? Could it be the version of the connector? If not what else might it be?

RE: Tomcat Crush
Howdy, Perhaps it is worth your time to try a different connector. But I think it's more worth your time to be able to reproduce this consistently. Have you searched Bugzilla for related bugs?
