[Jetty-support] OutOfMemoryException Perm Gen

[Chris_V <chr...@si...>]

Hello,

I'm running an application using an Exist XML database on Jetty 5.1.4. A
feature I want is to shutdown my application using the Jetty Admin servlet
without stopping the complete server. This is working great until I restart
the application using the admin servlet. Using jconsole, I see my Perm Gen
memory usage increasing on every startup of my application until I get the
mentioned OutOfMemoryException. Now, what I believe that happens is that the
JVM does not Garbage Collect the classloader used by Jetty to load my
application. As a result, my application's classes stay fixed in memory.
However, I'm pretty sure my application threads are all terminated before
the application is closed. Does anybody know how I can tackle this problem?

With kind regards and many thanks

Chris
