Hi Ming: TIPC 1.7.5 should allow you to have your third process receive messages from the other two processes using 2 different sockets. If this isn't working properly, then there's a bug in TIPC we need to fix. However, it may also be that your software isn't using TIPC properly -- this sort of thing has happened before.
Can you supply us with more information about exactly how you're using TIPC sockets? TIPC works differently depending on the type of socket being used (SOCK_DGRAM, SOCK_RDM, SOCK_STREAM, or SOCK_SEQPACKET), the type of addressing being used (TIPC name vs. TIPC port id), and the type of distribution being used (unicast or multicast). Sample code would be extremely helpful in allowing us to spot design or coding problems, or to try reproducing your problem.
