Key points is "Samba" and "Linux". When you edit files via Samba
share, it tries to lock files with fcntl(F_GETLEASE) if running on
Linux. This in turn results in errors while opening such "locked"
files. For more information see Samba docs here:

http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/locking.html#id2616903

It's not clear why the problem happens with files you didn't
changed, but I would suppose they are at least open via Samba.

Anyway, disabling appropriate locking in Samba configuration will
likely help. See the link above for details.
