Emmanuel Lecharny updated DIRMINA-722:
--------------------------------------
Fix Version/s: 1.0.11
> SocketAcceptor.unbind can hang when unbinding only one of several service adresses
> ----------------------------------------------------------------------------------
>
> Key: DIRMINA-722
> URL: https://issues.apache.org/jira/browse/DIRMINA-722
> Project: MINA
> Issue Type: Bug
> Affects Versions: 1.0.10
> Environment: Centos 5.3, JDK 1.6.0u11
> Reporter: Rhys Yarranton
> Fix For: 1.0.11
>
>
> If a SocketAcceptor
> - has multiple service addresses bound and
> - you unbind one of them and
> - disconnectOnUnbind is true and
> - the one being unbound has at least one session connected and
> - some other session on the acceptor also has at least one session connected
> the unbind call can hang. Excerpt from stack trace below.
> I suspect the hang is coming from IoServiceListenerSupport.disconnectSessions. The sessions to be closed are in the sessions variable, which is a subset of managedSessions (line 280). However, at lines 306-309, it is waiting (forever) for managedSessions to be empty. This will never happen.
> This is 1..0.10. The 1.1.7 code is different (it uses a countdown latch), and looks OK.
