Hi, I’m new here and now running couchbase server and using php sdk

We got warnings like below, and I’m wondering

  1. what does it mean
  2. and what happen if I disable socket pooling (https://docs.couchbase.com/sdk-api/couchbase-c-client/group__lcb-cntl-settings.html#ga23142cc1e082926148dcca86b841d3c2)

When pooled socket dead, and then it takes some time to create or get one pooled. It takes some time long, so I want to speed up by resolving those warnings.

Now using Couchbase Server CE 6.5, and pecl install https://packages.couchbase.com/clients/php/couchbase-3.0.0.tgz .

Plesase help me.

Thansk!
