Comment 2 for bug 1643328

I too had ran in to this before. Seems this happens when at least one node fails introspection, specifically when the IPMI address cannot be reached. When the page is refreshed, the UI will show no introspection data on the node. There is no UI indication that introspection did not complete successfully. I think this is specific to the UI, since command-line introspection will eventually time out and fail if an IPMI address cannot be reached.

I'm not able to reproduce this right now but if I have the bandwidth to do more tests soon I'll see if I can recreate it and get more logs.
