Couchbase connections graph showing more than CouchbaseMaxPoolSize connection?

Hi

Actually For particular bucket couchbase connections graph shows 600 connection and we set CouchbaseMaxPoolSize to 50 connection. How it is possible…!! Can anyone help to undestand this scenario.?? Why connections graph shows more than CouchbaseMaxPoolSize connection.!!

Please find below configuration.
Server Nodes : 2
CouchbaseMaxPoolSize : 50
CouchbaseMinPoolSize : 10
