Description Sebastian Witt 2004-03-11 05:04:13 UTC 
samba-3.0.2a compiled with gcc 3.2.2 on Linux 2.6.1 (libc-2.3.1).
Client: W2K SP4

When opening a new connection (new explorer windows) and displaying or searching
for files on a share, the other connections (file copying,etc.) are terminated
and smbd panics:

any chance you could try on a later 2.6 kernel ?
Sounds like a kernel bug to me.  Thanks.

Now tried with:

the same message:

I've attached the log file.
