Next time, please run with increased verbosity (-v 4) with output into
log file (-o dump.log) and provide the dump.log.

Oops :( It's a but in cr-check -- error from netlink diag engine isn't

the kernel according to http://criu.org/Installation? If yes, then you
must load all the *_diag.ko modules.
