Hi Allan,
Thanks for the reply,
I have got the name table entry when this issue was seen. here it is
root> tipc-config -nt |grep 1.1.5
553707482 10240 10240 <1.1.5:2228833412>
2228833413
<1.1.5:520270085>
520270086
655370 655370 <1.1.5:2219147253>
2219147254
<1.1.5:520257525>
520257526
2181056512 2181056512 <1.1.9:2560015065>
2560015067
10240 10240 <1.1.5:2227425003>
2227425004
<1.1.5:520257378>
520257379
10240 10240 <1.1.5:2227424980>
2227424981
<1.1.5:520257358>
520257359
It seems that both ports : 1f02 7ff5 -------------- 520257525
8445 7ff5 ------------ 2219147253
are availabe in the name table, what I understand (please correct me if I am
wrong) is these are not multicast messages.
It seems that some times previous port values are retained even after
re-starting tipc application.
I am not sure if this could happen.
Thanks
Jitendra

Subject: RE: [tipc-discussion] TIPC Messages are Sometimes beingmis-directed to
the wrong TIPC destport
Hi there:
On initial inspection, I can't see a clear indication of a problem. The
two messages you dumped both appear to be valid connectionless messages
that are being sent to TIPC port name {285213679, 655370}; the first
message has been mapped to port ID <1.1.5:520257525>, while the second
was mapped to <1.1.5:221914753>.
This sort of multiple mapping will happen in TIPC if you have bound the
same TIPC name to two or more sockets; TIPC will distribute the traffic
between the destination ports on a round-robin basis. However, the fact
that the two destination port reference values are identical in their
lower 16 bits (i.e. xxxx7ff5) makes me suspect that the upper 16 bits of
the destination port field of the message header have become corrupted
somehow.
So my advice to you is: a) print out TIPC's name table to ensure that
you don't have multiple instances of the TIPC port name you're trying to
send to, then b) upgrade your setup to use TIPC 1.5.12 to see if that
makes any difference. (The TIPC change history doesn't indicate that
any fixes were made that would address your problem, but it's normally a
good idea to run the latest version of TIPC just to be safe.)
Regards,
Al
