Second node slowing down
sheckler Nov 22, 2004 6:53 AMHi,
I am running a cluster of 2-4 nodes of JBoss 3.2.6 with HAJMS. Within the development environment (W2K on pcs) everything works fine.
Within the target environment (Solaris SunOS 5.8) the second node is slowing down dramatically, while deploying the clustered ejb components, but no error or warning is logged. After a long time (some hours) the second node comes up successfully. The second node is started after the forst node has started successfully. The network people told me, that everything was fine for them.

Does anybody know the reason for that behaviour?
