[Samba] System crash caused by nmbd

[Britta Tautermann]

I've got Samba 3.0 running on a linux machine (red hat 9).
the server is configured as PDM with five windows xp clients connected to it.
all day long, when there'S activity on the server it runs without problems,
but during the night always the same error occures and causes a system crash on the server.

here the relevant part of the logfile:
