Maximum connection to port 11210

Couchbase Server
1

Hi,

Currently I have issues with my query node, it can not connect to data node due to max connections in port 11210 (30k++)
I’m using couchbase 6.0.1

  1. How to increase that max conn setting?
  2. What’s the possible cause of connection leak for this port?
  3. How to recover / clean the connection?

Thanks!
