[CRIU] dump failure msgs

[riya khanna]

I'm trying to dump a container and I see the following errors:

(00.238188) pid = 333 getpid() = 1975

(00.238256) pid = 333 root_item->pid.real = 84

(00.238353) Error (namespaces.c:159): Can't dump nested mnt namespace for
333

(00.238432) Error (namespaces.c:355): Can't make mntns id

This is the output of ps

   84 pts/0    S+     0:05 /sbin/init

  333 pts/0    Sl     0:09 /bin/server

What could be wrong here?
