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.
