Crash with Samba 2.0.6

Wed Aug 16 12:26:10 GMT 2000

Hi!

Short time ago our Samba-Server crashed during normal use with low load.
(Ping was working, but no login was possible (didn't ask for password on
the terminal)).

Perhaps it is a bug, or perhaps it is a problem with my machine and you
can help me.

I am running:
SuSE Linux 6.4
Samba Version 2.0.6 (smbd)
Kernel: 2.2.14 (original SuSE-Kernel)

Some Logfiles:
