Re: [jetty-users] Jetty server periodically looses Freemarker template
Are you on a unix machine, using default /tmp directory for java.io.tmpdir ?
It is likely that some process on a unix machine is clearing out or deleting content in the standard /tmp directory.

If so, either specify a java.io.tmpdir to be somewhere other than /tmp 

  $ java -Djava.io.tmpdir=/var/run/jetty -jar start.jar

or create a "work" directory under your ${jetty.base} (if running Jetty 9.1+)
use ${jetty.home}/work/ if running versions of Jetty prior to 9.1

I have a Jetty Server that normally works well but hiccups every few
days,  causing a service to go down.  I could use some help tracking
the problem down.

This server has two web applications that live on two different
name-based virtual hosts,  each of these is packaged in a separate WAR
file.  One of these services runs like a champ and never has problems,
 even when the other one fails.  The problem goes away for a while if
I restart jetty.

When the one that fails fails,  I see this exception over and over
again in the logs:

Any idea what I can do to track a problem like this down?
