We’re using 2.5.1 Community edition. After one of 24 nodes was failed over due to network problems I added it back and started rebalance. Rebalance is at 0% for 4 days so far and it does not respond to cancel. UI logs are full of those (useless?) “Metadata overhead warning. Over 62% of RAM allocated to bucket “XX” on node “XXXX” is taken up by keys and metadata.”
Please help as this is a serious problem for us.
