This specific case uses 3 peers connecting two channels each, with the channels not sharing a transport. One is UDP, one is TCP. My recommendation is to ignore the 2 channel part, since they are not using a shared transport. So, test multiple peers (i.e. > 2) with a UDP config matching the "jbm-control" config shown at http://viewvc.jboss.org/cgi-bin/viewvc.cgi/messaging/branches/Branch_1_4/... The call pattern is connect, then getState. Recommend isolating the problem using that setup; once that is done testing can be expanded to include permutations like connect+state transfer and shared transport.
