This is part of the log and strace output from samba 3.0.9 running on kernel 2.4.27.
The output from samba 3.0.8 on kernel 2.6.9 looked somewhat similar...
I haven't seen much on the list or ancilliary documentation recently, other than
 "it is fixed for samba > 3.0"...  Could someone please shed some light on this?
