[CRIU] dumping LXC 1.0 container failed - unable to open irmap-cache: No such file or directory

[David Shwatrz]

Christopher,
Yes, you are absolutely right. In tests which I had done with a simple
process (not  in a containers environment), everything with c/r worked
fine, but this same message still appeared.

>Error (mount.c:430): Mount 327 (master_id: 2 shared_id: 0) has >unreachable sharing

Any ideas how can we tell to which mount/mount point is this message related ?

Regards.
