What I'm seeing is this; Okay, something funny is going on, but I don't know what yet. That assertion is coming from liblxc.so->libgnutls->libgcrypt and seems to be complaining that we're unlocking something that is already unlocked. So I compiled lxc without GNUTLS support (by commenting out the check for it in configure.ac) and now I get past that and get hangs similar to yours. Interestingly, I modified your program to just do the create and destroy and not the start nor stop and I still get the hangs during the creation part. > * lxc-test-concurrent get stuck > > [caglar@qgq:~] sudo lxc-test-concurrent > Executing (create) for 5 containers... > > * ps auwxf shows this (so no rsync etc. running anymore) > > caglar 21004 0.2 0.2 51344 4868 ?
