I'm doing this infact, an udp server to handle udp request from jetty 
and write on serial link.

My application isn't a public web-server, but  running on a private lan,
intrusions aren't impossible.

It's running on 
S.O    : linux Red Hat 7.3, 
jre    : sun 1.4.0_01,
driver : IBM comm-api for linux (they were never upgraded )

Thank's for all Martin and Davide, i also think the problem was on 
serial driver,
the only thing i can do, is to add new udp server and try with it.
