[BUG?] sshd closes the connection after 2^16 bytes

Hi,
I'm having trouble with the sshd on one particular machine. In short:
$ head -c 196481 /dev/zero | ssh machine-name 'LANG=C wc'
0 0 65536
(the 65536 here should have been a 196481 ...)
This happens whether I launch the command from the machine, or from
another remote machine. The OpenSSH version is:
OpenSSH_4.3p2, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008
with:
$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.4 (Tikanga)
$ uname -a
Linux machine-name 2.6.18-128.7.1.el5 #1 SMP Wed Aug 19 04:08:13 EDT 2009 ppc64 ppc64 ppc64 GNU/Linux
One surprising thing:
$ head -c 196481 /dev/zero | ssh machine-name 'LANG=C wc'
0 0 65536
$ head -c 196480 /dev/zero | ssh machine-name 'LANG=C wc'
0 0 196480
So, the bug is triggered when sending 196481 bytes or more, but the
consequence is a truncation of the input at 65536=2^16 bytes.
Any idea what's going on?
Thanks,
