21:46 < jibel> stgraber, the problem is still there with cgmanager 0.32-4ubuntu1
21:47 < stgraber> jibel: now that's something I wasn't hoping to hear :)
21:47 < stgraber> jibel: so I'm guessing the same dbus-send test hangs against cgmanager/sock and not against cgmanager.lower/sock, right?
21:47 < jibel> and the logs are not more interesting to read
21:48 < jibel> stgraber, yes, same result.
21:49 < stgraber> jibel: ok, what happens if you "pkill -9 cgproxy", does that fix it?
21:51 < jibel> stgraber, it does
21:51 < ogra> wow, i didnt know you could tear it out uderneath without losing anything 
21:52 < stgraber> ok, so that seems to confirm that it's the proxy getting confused somehow
21:52 < stgraber> ogra: yeah, you can shoot them in the head, they'll respawn and nobody should notice, we had to implement that so you can dist-upgrade the host and not kill all your containers in the process
21:52 < ogra> neat
21:53 < ogra> so worst case we could just introduce a watchdog as workaround 
21:53 < stgraber> so one thing I notice in the log and that's not supposed to really be a problem but may be making things worse at the moment is that we're dealing with a long running connection to cgproxy there which isn't very usual
21:53 < stgraber> upstart and systemd-logind both establish a new connection every time they need to talk to it rather than keeping a long running one around
21:54 < ogra> who is that keeping the constant connection atm ? upstart-app-launch ? 
21:54 < stgraber> it may be worth patching whatever's talking to cgmanager to do that too and see if that helps. Don't get me wrong, there's still a cgmanager/cgproxy bug somewhere, but short of having hallyn around, this may take a while to track down so if connect/disconnect does the trick, that may be an easy way out.
21:55 < ogra> ted, ^^^ ?
21:55 < stgraber> don't know, I don't think I've seen a log with the app name, only its pid :) but yeah, whatever calls gettasks all the time :)
21:55 < ogra> well either qtmir or UAL 
21:55 < ogra> i guess
21:58 < pmcgowan> stgraber, ogra good stuff, can we get all this in the bug report?
21:58 < stgraber> probably, what's the bug # for that again? I was given at least two different ones for this this morning
