=A0i have encount= ered a peculiar issue in cassandra
i have 2 seeds and 2 nodes
all the= 4 nodes carry the same 2 seeds in the storage-conf.xml
so they discover each other once started, but the problem is after they dis= cover each other
But after a while
nodeprobe shows that the other 3 nodes are down on eac= h one of the 4 nodes, ie only the current node is alive

is there a w= ay to do a keep-alive kind of thing between the different cassandra ndoes
