Which brings to mind a question.
What are the benefits of packaging a webapp as a WAR and letting Jetty
automatically unzip it? I used to, and I still use Eclipse to package my
webapps into WAR files to ensure that all of the dependencies get
packaged with it, but now I just manually unzip it on the server and
then restart Jetty.

I agree with Stefan and Michael.
Its a /tmp directory cleanup issue. (quite a common problem seen when
using long running, platform neutral, services on linux)
Like Michael said, set the java.io.tmpdir system property that Java
uses to a directory somewhere other than /tmp. (the system admins
should have a few preferences for you, depending on your linux
distribution. (some commonly seen example: /var/cache/jetty or
/var/www/jetty or /home/jetty/work)
This will influence the behavior of Jetty itself, and velocity.
Jetty will then use the new temp directory for its own unpacked webapp
structure (a process that which is required in most deployment use cases).
And when velocity itself needs a temp directory for its own reasons
(which it does) those files will also remain untouched.
Also if you have any other 3rd party libraries that use the Java temp
file routines those will also reside in an location untouched by other
processes.
Additional suggestions:
* Upgrade Jetty - 9.1.x is part of the transitional period for Jetty
9 from Servlet 3.0 to Servlet 3.1. Its a bit of a hybrid release.
* Once you have upgraded, use the ${jetty.base} and ${jetty.home}
separation.
* After creation of your ${jetty.base}, make sure you have a
${jetty.base}/work/ directory created as well.

Thank you for the reply Stefan,
But the people that set up the servers told me there's no tmp
clean up.
Can you think of another reason?

Sounds like the linux tmp folder is cleaned up every now and then.
You can make jetty use a different tmp folder in order to prevent
issue. See docs.

Hello,
We are having loads of "Unable to render Velocity Template"
throughout the jetty logs. Then the user can't see the site anymore.
2015-01-26 10:20:38,751 [qtp399631128-23 ERROR CommonsLogger]:
Unable to render Velocity Template, '/error.vm'
org.apache.velocity.exception.VelocityException: Exception
rendering #parse(/_inc/footer.vm) at /error.vm[line 67, column 9]
...

2015-01-25 23:07:34,732 [qtp1819130381-4849 ERROR CommonsLogger]:
Unable to render Velocity Template, '/super/aba_vitrine.vm'
org.apache.velocity.exception.VelocityException:
VelocimacroProxy.render() : exception VM = #produto()
It happens a few times a month. When this happens the only way to
bring our frontend servers back is to restart jettys.
This started to happen when we updated from jetty 7 to jetty
9.1.3. Could this be a jetty parameter or something?
Thank you,
Eduardo Fiss Beloni
