Hi,
Is there a known problem with checkpointing in OpenVZ kernel 2.6.22?
I'm getting the following errors:

Yes. Hopefully CPT will be back in 2.6.24 branch.

As far as I see from the err variable initialization
the dn_nl_deladdr() routine was designed to report errors

But the code sets this err to 0 after the first nlmsg_parse

Currently the network namespace work has gotten about as far as we can
without the ability to make sysctls that are per network namespace.
The techniques we have been using for other namespace of examining
current and replacing the ctl_table.data field depending on the
namespace instance that
There are a number of modules that register a sysctl table
somewhere deeply nested in the sysctl hierarchy, such as
fs/nfs, fs/xfs, dev/cdrom, etc.
They all specify several dummy ctl_tables for the path name.
This patch implements register_sysctl_path that takes
an additional path name, and
By doing this we allow users of register_sysctl_paths that build
and dynamically allocate their ctl_table to be simpler. This allows
them to just remember the ctl_table_header returned from
register_sysctl_paths from which they can now find the
ctl_table array they need to free.

This patch implements the basic infrastructure for per namespace sysctls.
A list of lists of sysctl headers is added, allowing each namespace to have
it's own list of sysctl headers.
Each list of sysctl headers has a lookup function to find the first
