Re: [jetty-users] Jetty server crashes
Kapil,

If you are running on Linux check the system log for kernel panics due to lack of memory. Linux will ruthlessly kill the process with highest memory load in such a situation. That has happened to me plenty of times and also left me wondering where my JVM process had gone.

And to add to what Greg said: the System.exit thing can also happen in a library. I used a library once that would do a System.exit in some error situations killing my server now and then. That was a real puzzler.

Cheers,

Silvio

Greg,

Actually below things are observed:
  1. No process of jetty server running
  2. MySQL still runs
  3. CPU usage shows data fine
  4. RAM is also fine
Not sure how can we isolate if issue could be because of JVM, can you please guide on setting some parameters or moniotring them.

Thanks

Kapil,

I'm sorry but you've not given us enough information to say anything.  What do you mean by "crashed"?  If it is the JVM that stops, then that is not a Jetty problem.  Is there a stack trace? Is there any logging?  Is the process still running? Can any requests be served? Is the connector still listening?  Can you run with debug?  Why do you think it is jetty and not some other component?

regards

We are using jetty server and when it is on load then the server is crashed without showing much of information.
We have also put it on JMX. The CPU usage and memory looks fine, but still Jetty server crashes. Please let me know what parameters we should look for and how can we isolate issue which is causing jetty server crash.
