TIPC issue : reproduced with relevant syslog entries...

Hi all,
 
We need help with a problem we are observing with reception of TIPC names in a simple 2-node network. 
 
Setup: Two nodes running TIPC 1.5.08 on 2.6.10 kernel on Pentium3 machines.
 
Problem: Node 1 binds a few names (more than 9 to 10 of them) and, after that Node 2 comes up and tries to receive the publications. The reception of publications are failing (see for e.g. the "overlapping" publication reported in red below).
 
[The TIPC messages dumps are available, but I have not included them due to their size.]
 
Thanks,
Phani
 
PS:
(1) The following mail below contains -  System-log (containing custom-enabled TIPC log), name-table dump and link statistics on Node-1 and Node-2.
(2)  Jon, Al, this is the same problem that one of our folks, Surya, reported recently and it is still under investigation.
