This sounds suspiciously much like the Ethernet maximum packet size,
which is just 1500 bytes when using TCP/IP.  This would seem to
indicate an IP fragmentation in your OS kernel.  Since all versions of
Solaris 2.0 <= x <= 2.4 are notoriously buggy (2.5 and 2.5.1 seem
reasonable), I would suggest either upgrading to Solaris 2.5(.1) or
installing the latest patch cluster from Sun, available from
<http://sunsolve.sun.com/>.
