No Context Configured To Process This Request

Hello;

I have a Java Application running on Tomcat. Twice now, I will go to call a servlet during a period of time when everything was working fine and get a HTTP Status 500: No Context Configured To Process This Request.

When I check the processes running there is no Java process running.

A restart of Tomcat fixes it.

Is something not configured correctly? How can this happen during processing? Could a process hogging too much memory cause this?

Thanks,

Luke

It sounds like Tomcat crashed but your webserver & connector were still recieving the requests.
Or... are you running Tomcat as a standalone?

What does that mean running it as a stand alone?

standalone:

This means you are running Tomcat in isolation rather than piggy-backing it to Apache.

Ah, ok.

I am using mod_jk to forward request from Apache to Tomcat, so I guess the answer is no.

I guess what I am looking for is the best way to go about trouble shooting this. It happens intermittently and the logs aren't telling me anything. Could this be a mod_jk config issue? Could a very heavy Java process being repeated cause Tomcat to crash?

Thanks,

Luke

I'm surprised that Tomcat is crashing without anything going to the logs.
Are they empty?

Well the localhost log doesn't contain a whole lot.

I have log4j configured.

All my packages have appenders and write to specific files. I have search them for errors and not found anything.

I hope I am not losing any log information the way I have it set up.

This is probably a dumb question but I've thrown it out before and had it hit the target really.:

Is there anyone on that machine who might be typing "killall java" to stop a process?

I don't think this is the case.

I think I have a memory leak somewhere in my application. After a couple of days I think the whole thing just crashes.

My solution for now is I am going to put a cron job on the server that restarts Tomcat every 48hrs very late at night.

This should take care of it.

Thanks for the help,

Luke
