First off.. I have no clue what SX-6 is.. Nor what hardware it runs on.
Nor how old it may be.  So it would be nice to be clued in on that.  Maybe
even what branch of the UNIX tree it was formed from.

Don't know.  Most of the time I've seen 'Bad Packet length' it was a
broken OpenSSL.  IIRC in the OpenSSL tree there is a 'make test' that
allows you to see if everything passes.

My tired and befuddled brain wants to say scream out 'race condition', but
even after skimming your last emails.  I really am not sure off hand.  I
know AIX has oddities under some releases for select().

I wish I could give you more direct help, but at this point.  I'm not sure
what to even suggest for a starting point.
