Can you try to session.close(false) just in case after the waitFor on
the channel ?

I have a test case that connects to a Karaf 3.0.2 server via SSH to
reset the environment prior to making WebService calls to the server.
After upgrading from Karaf 2.3.4 I started noticing
"java.lang.OutOfMemoryError: Java heap space” errors. In looking around
I noticed 60,000+
org.apache.karaf.shell.security.impl.SecuredCommandProcessorImpl objects
in the HeapDump when the Karaf server had only run a few rounds of testing.
1) Although I have searched without finding a definitive answer, Is this
a known issue?
2) I am using the default Karaf 3.0.2 installation with cxf-jaxbws and
some custom bundles. In addition to the attached screen image from the
Eclipse Memory Analyzer, what additional information should I provided?
