Comment 3 for bug 1021471

Sorry, I don't yet have a recipe for reproducing it.

I did manage to get the system into the broken state again after I filed this bug report by suspending/resuming and starting/stopping/using containers as usual, but I can't trigger it on demand.

As for heavy load: not at the point it breaks. The main container I use is one I'm working on some Launchpad changes in. I often run the test suite inside it, and I guess that is rather heavy.
