Description Koen Kooi 2012-01-24 04:04:11 UTC 
Zypper doesn't do anything on my system but hang, even 'zypper help' doesn't return anything. Strace reveals that it's hanging in a futex right after RT access has been denied. On my system I disallow RT access to everything except a single app that actually needs it.
Comment 1 Mark Hatle 2012-01-25 08:20:49 UTC 
What are you using to deny the RT access?

(Futexes are used by the internal locking, but I don't know why anything would be using RT within Zypper.)

It's a systemd feature: http://lists.freedesktop.org/archives/systemd-devel/2011-November/003793.html

The RT thing might be a read herring, I'll try to strace it again and attach the log

No further info on this, nobody has been able to replicate it recently.
