CA PPM - Multicast Works with jGroups but not with Tower Shell

Hi All,

 

Long time I haven't posted here.

 

Another problem regarding Multicast on CA PPM 15.3 (Patch 2).
I have 3 servers on the same subnet as01, web01 and web02 (IP 10.114.12.130,131,132).

 

No Database Connection has been set yet, it's a fresh install.

 

Multicast works correctly between servers with jGroups Library (see logs below).
But admin tower returns randomly either no server, either localhost server.

 

I reviewed every step mentioned in the very good articles :

kb000023660

kb000048555

 

I even tried increasing Xms/Xmx parameters on beacon service in .setup/script/commondeploy.xml.
But still no luck.

 

Could there be a problem with UPD Ports ?

 

Thk,
David

 

Test on Multicast Adress 239.0.0.1 and 9090.
