Hi,

Please read through the following post from this forum on a similar issue, but related to a driver version mismatch:
SQL Developer 3.2 - Connection reset

If that does not apply, then the mismatch may be something you can fix by changing some settings -- the following thread provides additional advice and reference links:
Re: Encounter "SDU mismatch" while trying to connect to a database

Hope this helps,
Gary
