OK... So I ran the test again... and this time, here is an interesting 
error message I got in my server log:

[2007/04/15 21:36:10, 8] smbd/dosmode.c:dos_mode(377)

Sooo... Seems smbd is running out of memory. But I get no "out of 
memory" errors on the system console. So could it be running out of 
allocated memory (in which case, is there a kernel parameter that I can 
set to enable more memory per process)?

Thanks,
Gilles.
