But I think I used this line before and removed it later because I saw some posts in the forum saying that this is not necessary since a fix was made in mina. There is no fix in MINA to solve what is not an issue. If you set the ReuseAddress parameter, then you have a workaround. But this can't be the generic approach. Usually, you must try to stop the server closing all the connections, otherwise you get stuck with this error until all the socket in TIME_WAIT state are freed by your systeM; And it can take a while (300 seconds AFAIR on linux). You can also set a lower time for such timeout, but this is not necessarily a good idea, from the security POV. Some good explanations about this situation : http://hea-www.harvard.edu/~fine/Tech/addrinuse.html -- Regards, Cordialement, Emmanuel Lécharny www.iktek.com
