Network failure with a pair of symetrical stack TCP

[leug85]

Hello,

I use a jboss cache (TreeCache 1.4.0-SP1-jdk50) in order to share some result between two servers A(gtar1) and B(paplx2).

My configuration is the same that described in that page :
http://wiki.jboss.org/wiki/Wiki.jsp?page=JGroupsStackTCP


my problem is during a network failure. The two node detect that there are alone. But when the network go up, the members never change so the two server are still alone.

in order to simulate the network failure, I use this commande :
iptables -A INPUT -s gtar1 -p tcp -j DROP ; iptables -A OUTPUT -d gtar1 -p tcp -j DROP ; iptables --list


here is the trace of org.jgroups and org.jboss, the network was up at 11:34:20 :
Server A:
http://barbalum.free.fr/serveurA.txt
Server B:
http://barbalum.free.fr/serveurB.txt

Sorry, the end miss :

Is my config wrong ?

Is it link with the shun mode of FD or GMS ?

Is it link with the fact that I have only 2 hosts ?

thanks for help.
