so far seems downgrade of sudo helped, one from th-archives

the actual fix was to upgrade away from buggy kernel

broken:
2.6.36.2-1
util-vserver-0.30.216-1.pre2955.3.x86_64

better:
2.6.37.6-2
util-vserver-0.30.216-1.pre2955.3.x86_64

2.6.37.6-2 on the other hand has other bad behaviour, like two vservers sending to each other lots of concurrent http connections, made apache processes stall in D state (mostly the main watcher), lots of Z and port 80 unresponsive for several minutes, when it just recovered.

actually the http connections were coming off the internet, same "lockup" was noticed, so far had to downgrade to 2.6.36.2-1 kernel and sudo-1.7.4p6-1.i686 to continue normal work
