In the period of a week now, I've seen at least four different people
report this exact problem (and I'm one of them!), and I respect that David
Collier-Brown yesterday posted a thorough message trying to explain the
problem, and how to diagnose it, but I don't buy that there is bad hardware
or network misconfigurations.  Everything else to do with networking is
going fine - no interrupts, no resets, no crashes, etc... and the network
load really isn't *that* heavy at all.

The last thing that I tried was to change the ethernet driver from the
3c59x to the 3c90x for the 3Com 3C905C ethernet cards that are in the
system (even though I have a number of other systems with these cards using
the 3c59x driver just fine with no errors).  That didn't help, either.

I've tried playing with 'socket options =' with no luck.  The default
'keepalive =' setting *is* 0, and the systems are not crashing, bombing,
rebooting, etc at the time of these errors, either.  But still, my other
Samba networks don't even report any errors when those systems *do* crash,
bomb, reboot, etc.

So, I honestly think that there is a bug somewhere in Samba.  I posted the
code to the list for the write_socket_data routine, cause I don't know C,
and nobody even mentioned it.

Anyway... I'm just trying to say that I think there is something going on
here, and I wish that someone would take notice.

Thanks.

Lee.
