Re: [jetty-users] jetty dies periodically

[Joakim Erdfelt <joakim@xxxxxxxxxxx>]

First, setup a JETTY_BASE.

Don't skip this.

Don't modify the jetty distribution.

This is important, don't avoid this.

Future versions of Jetty will only support a proper JETTY_BASE vs JETTY_HOME split.

Next, don't use -Djava.io.tmpdir=/tmp on ubuntu, that's not going to work for services that last longer then 2 hours (as ubuntu cleans out the system /tmp directory periodically, breaking many java server libraries)

Next, create a $JETTY_BASE/work directory, and do not specify -Djava.io.tmpdir.

Let Jetty control its own work directory.

Next, move the following command line options to your $JETTY_BASE/start.ini (or equivalent $JETTY_BASE/start.d/*.ini file)

jetty.logging.dir=/opt/jetty/logs   // <-- this should be your $JETTY_BASE/logs directory

jetty.port=7070

Next, remove jetty-logging.xml from your command line (that's 100% inappropriate there).

Apologies for being vague. What I see is thus: I start Jetty with "service jetty start". I deploy a WAR (it's a simple CXF REST service), test it, debug code, redeploy. Through all of this I'm tailing the *stderrout.log and periodically see nothing logged when I redeploy the WAR. When this happens I do "ps -ef | grep jetty" and find no JVM running. Would you classify that as a crash or an exit? I'll call it a crexit until I know more. I do "service jetty start" and it starts back up and the whole cycle repeats. What do I expect? I'll take that as a rhetorical question from someone who kindly helps others here but grows weary of noobs, as I probably would, too.

I'll enable DEBUG logs and will report back. Thanks for your help.

You have to be more specific. The JVM process exits ? JVM crash ?
What do you mean by "the service stop" ? What do you expect and what
happens instead ?

We have Jetty running in Ubuntu as a service like you have, running
happily for months.

If you enable Jetty DEBUG logs, what do you see before "the service stops" ?
