[CRIU] crtools error checkpoint/restore error ("Unable to open pstree.img")

[Kevin Wilson]

Hello,
Strangely, there is no /proc/940.

Maybe this process was killed ?

I will try again this test from scratch, after rebooting,
and dumping before all entries under /proc to see
whether it was killed by checkpointing.

Best,
Kevin
