Ok, probably not the best idea. I wanted to start the code that does
JDBC connection management on my machine and see if I get similar
problems.

I posted your original message to IB-Support group, maybe we get some
replies there. In meantime, can you check what sockets are opened on
that server? Can you also check that your application does not try to
open non-existing port all the time?

Something that is promoted on the site you referenced in one of your
posts (Java Service Launcher). I thought it is somehow connected to
your problem.
