Message-ID: <4A5F1104.2070509@rambler.ru> (raw)

Please CC me: I subscribe and get ignored by the mailing list periodically..

If other parts of the message are needed, let me know.

dmesg after such a problem kills system immediately; system hangs on its
own after some times.

It usually happens on symlink-intensive operations (creating tens of
thousand of symlinks inside some tree).

I also have some more ghost files now..
