Hi Shreedhar, thanks in advance for your answer. Two things make my crazy about the issue:
1. The antivirus does not combine a firewall.
2. The hang only happens in stress situations, a.k.a. when I launch many clients (swing remote EJB3 + JMS applications). When those apps start, they lookup for some remote references for EJB3 session beans, and subscribe to a topic with diferrent selectors. Sure this causes a lot of socket creation, and perhaps because of these the antivirus blocks socket creation or something I don't know what, and I don´t know how
