Yes, they support remote locking.

Maybe a missing capability?
>you did test that it works on the host, didn't you?
Yes, of course I did. On the host, locking works fine.
Both inside and outside the container, access to the file is blocked when
the file is locked by another process. But outside vserver, a blocked
process is waked up immediately when the lock is withdrawn. Inside the
container, the processes do not wake up immediately, but pause for minutes
until they get the lock.
>btw, what kernel/patch/util-vserver version?
Sorry, I forgot to mention. The system is a Debian GNU/Linux 5.0.3
i386 with all current security updates. The used packages are
linux-image-2.6.26-2-vserver-686_2.6.26-19
util-vserver_0.30.216~r2772-6
vserver-debiantools_0.6.3
According to the kernel package changelog file, vserver patch version number
is 2.2.0.5. Can this be verified from /proc or /sys?
Regards,
Harald
