I found a very strange bug when cleaning the http proxy.
What I did: I cleaned the web proxy via the "Clear Cache" button. Coincidentially in the background there happened a proxy request while the cache was cleaned:

The proxy had to be started manually after that, since it didn't come up automatically for > 30 seconds (was restarted at 02:00:xx by me manually).
Unfortunatelly I could not yet manage to reproduce this bug; probably only happened because of the access while shutting down the cache.
Since I could not reproduce this, I cannot tell for sure if it has something to do with the access inbetween or if the problem is related to a special moon - jupiter - earth constellation only happening every 1.5 billion years for 30 seconds; but this is the only thing different from the other approaches to reproduce the bug.
Good luck with the bug hunt
