Hi Bertrand and Richard,
Did a further experiment after encountering the hang ...
ka...@root> list | grep Web
[ 3] [Active ] [ ] [ 30] OPS4J Pax Web - Jetty
Bundle (0.7.1)
[ 37] [Active ] [ ] [ 40] Apache Felix Web
Management Console (2.0.6)
ka...@root> stop 3
You are about to access system bundle 3. Do you want to continue
(yes/no): yes
ka...@root> list | grep Web
[ 3] [Resolved ] [ ] [ 30] OPS4J Pax Web - Jetty

Management Console (2.0.6)
ka...@root> stop 37

ka...@root> start 37

After that I WAS able to connect to the webconsole.
Start levels?
best regards,

Have been experiencing an intermittent hanging problem when I try to connect
to a felix web console. By hanging I mean - connecting to the url produces a
blank webpage - no errors just a blank page. Sometimes it works and other
times not (its around a 50% failure rate.) When I make a connection to a
newly started framework's webconsole and I get a hang the only thing I can
do is to restart the framework. (I am using Karaf with felix)...
Could it be that your system is stuck in a loop like FELIX-1967 ?
I've seen similar symptoms when experiencing that problem, the console
appears to be stuck because it's waiting on locks that are held for a
very long time due to Resolver.findConsistentClassSpace running in
circles.
If that's the case, thread dumps every few seconds would show that
method active at various stages, and CPU usage would be high.
