Someone recently posted a thread about a similar complaint to the lists
recently. IIRC, the [SOLVED] post mentioned a problem with MTU being
smaller than some of the packets received at one point, causing
fragmentation, and the next step not being to reassemble the packet
because of a certain flag being set.

I don't remember which bit the flag was and no little about this, but I
remember the general gist.

Maybe your problem is similar?
