I’ve deployed a three node Couchbase 7 cluster. When its is running then the consumed memory keeps increasing day by day. Htop reveales that it is solely consumed by some Prometheus process that seems to run internally within Couchbase.
Today it reached a consumption of ~45% of the nodes memory which is ~12.8GB.
After restarting the node and letting it join the cluster again, the prometheus memory consumption is at ~300mb again. Is this some kind of known issue. What could causes it, how can It be prevented?
