The following steps leads to an error when displaying Endpoints under the NMR advanced screen. 1) start servicemix 2) start NMR example - features:install examples-nmr 3) verify that HelloWorld endpoint is listed in UI 4) stop NMR example - features:uninstall examples-nmr 5) when the example has stopped the following error appears "Failed to retieve table data. Error in retrieving lice data from agent" In step 2 the nmr example I was using was a modifed version of the SMX nmr example with 10 endpoints and 20 threads.
