Ok. Just got some time to take the server(s) down and play with them.
Here are some results.
Completely commented socket options line = No change
Changed bonding mode from 0(no switch support needed) to 4 (IEEE 802.3ad
mode ) = No change
I was hopeful because the bonding development lists said mode 0 can
cause massive packet reordering on the clients. But even with a
standards compliant bonding mode there was no change :(
Furthermore, it seems that this problem is only from the Debian Linux
Samba Server to the Mac clients. From the server to a PC is not affected
regardless of the number of cards involved (1 or 2). I may take this
issue to Apple forums if nobody has any ideas since it seems to be a
very specific interaction between OS X, bonding, and Samba.
Any other suggestions?
