(CC'ing to lkml in hope on advise why I've got ksymoops error)

Hello Urban,

My Samba server behaves strangely.
Very frequently (but not always) when I try to create/copy
files from win box to linux samba server it says that file/dir
already exists or that connection terminated. It is indeed exists,
in case of a file it is of zero length. Subsequent copy with
overwrite succeeds.

It seems that smbd dies after it has created dir/file but before
reporting this fact to the client. New smbd gets spawned by inetd
then.

It might be related to newer kernel.
I am willing to track it further.

Samba: 2.2.1a
Kernel: 2.4.10

Also I've got two oopses so far. One of them decoded below
(my first ksymoops, I don't know is it done right on not)

--------------------------------------------
ksymoops 2.4.3 on i686 2.4.10.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.10/ (default)
     -m /usr/src/linux/System.map (default)
