Thanks for the update Karaf.
For the wrapper, you can use respawn (on Unix).
For the perm, it looks like a framework "issue" (we have to dig around).

Here are notes after playing with dev:restart:
1. Permgen still leaks
2. Works only in main karaf shell ( ie invoke bin/karaf ). When I
ran it as a service via wrapper and use bin/client to assess karaf
shell, dev:restart kill my karaf.
So it seems we need a cold restart.

It's already possible:
- in the console: dev:restart for 2.2.x version, system:restart for trunk
(3.0)
- for the MBean, it's in org.apache.karaf:type=dev in Karaf 2.2.x (restart()
operation), or org.apache.karaf:type=system in Karaf 3.0.0 (trunk, restart()
operation)

Looks like the permgen issue is here for a long time. How about
adding ability for karaf to restart itself ( Hudson, and eclipse can
do this i think ). May be via webconsole, or JMX
Eager to hear how we could implement such feature for karaf.

It is about feature to be loaded in and out of karaf dynamically. So
I guess is a known issue to 'java', karaf is not an exception :(
Wonder if ACE can solve this issue

Hi Dan,
just to understand your issues:
- if you talk about the feature service itself, I'm agree that it
shouldn't
consume perm
- but the loaded classes (loaded by the feature service) consumes perm,
and
it's a normal behavior (it's exactly the same with on Tomcat with
hot-deployment for instance)

Hello Karaf Team
Each time I reinstall/update a feature at runtime, my karaf loses some
permgen. Amount depending on number to classes I have. Is there any
one able to address this issue?
Setting JVM to -XX:+CMSPermGenSweepingEnabled
-XX:+CMSClassUnloadingEnabled doesnot help.
