The HTTP-Server bundle causes a memory leak when uninstalled.
Uninstalling and installing this bundle in sequence many times causes a growing memory usage of the JVM. Investigating with VisualVM reveals that many references are still reachable when they should not be. I found the bug, and I will send a patch.
Here is a patch that adds the missing cleanup code.
Many Thanks for the patch.
I have applied it to the trunk, revision 3863.
The first version of the http-bundle with this patch will be 3.1.4 available from the snapshot-build page later today: http://www.knopflerfish.org/snapshots/
