[CRIU] checkpointing xclock failed with Fedora 20: "Can't dump half of stream unix connection"

[Andy Johnson]

Hello,
I had made this test:
1) Ran xclock from a terminal on F20 X86_64 and find its pid, which was 18428.

2) Ran the following from a *different* terminal:
 criu dump -t 18428 --shell-job --ext-unix-sk

I got this error:

(00.020250) Error (sk-unix.c:478): Can't dump half of stream unix connection
.
(00.020385) Error (cr-dump.c:1811): Dumping FAILED.

Many *.img files were created in the folder from which I ran this
command, which means work has started for this command.

My question is: I assume this has to do with Unix sockets. Is there some more
option which I should pass to the criu command ?
should this work on criu 1.0 ? or should this work with the latest
criu from git ?

regards,
Andy
