connection time out

Hi All!

I have a linux clinet which connect to the remote posgtresql on a linux
too with a java GUI application.
This application read an write the database when a blockout occurs. In
this situation the java application
leave many connection in the postgresql (about 30). When the client is
restarting and try to connect to the database I get an
exception:

Caused by: java.net.ConnectException: Connection timed out

but the max connection in the server is 200. From the console I can
create many connection to the server (psql) just the java can't.

Someone have an idea ?

(postgresql 8, java 1.5)

Thx.
