I’ve installed percona xtradb cluster on 3 nodes and all is good until i noticed that 1 node is consuming memory much more the other nodes
So i decided to stop all traffic going to this nodes and check if the memory is going to be full again.
used memory 7517M
used memory 2669M
used memory 2574M
Also i noticed that on node 1 which consuming all the memory that innodb buffer pool is full even when its out of traffic.
What might be the reason for this ?
