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..
