Description Murray McAllister 2014-03-06 02:00:50 EST

Frantisek Reznicek of Red Hat reported that a change in or before qpid version 0.22 resulted in ACL policies only being loaded if the acl-file option was specified. This resulted in qpidd, by default, not checking the connection limit. A client could send a large number of requests to qpidd, resulting in the file descriptor limit being reached and qpidd refusing to handle further connections.
