> Undertow causes XNIO exception "Buffer was already freed" during response write, possibly due to premature client close.
> I suspect this may also cause the socket to leak, because the number of "Buffer was already freed" messages in widlfly server.log corresponds to the number of leaked sockets in the lsof command output for the wildfly process (seen as sockets with "can't identify protocol" description).
