We've moved from 2.4.25 to 2.6.3 and the nodes of our cluster can no
longer communicate. A node running 2.6.3 can get stats from a 2.4.25
node, but not the other way around. The 2.6.3 was configured using the
2.4.25 config file as a base, so all of the network settings are the
same. There seems to be something funky going on with the multicast
support in 2.6.3 and ganglia.
Any thoughts/known workarounds?
Thanks!
