We are running 3 Node Cluster, data in memory on version 188.8.131.52 CE. We recently noticed writes are not happening and found one down. Ideally write should happen. Once we start the node which was down, the writes resumed.
Found below INFO Logs being printed continuosly on two nodes.
INFO (hb): (hb.c:4319) found redundant connections to same node, fds 101 31 - choosing at random
On the other node, no logs being printed and no read/writes happening on adadm stats. Also we have observed that the records are unevenly distributed across the nodes.
