    Description

      https://forums.couchbase.com/t/couchbase-python-sdk-memory-leaking-for-simple-kv-get-operation/33069/

      I was able to reproduce the issue using the script provided by the user. I've attached a plot created by mprof that shows the constant increase of memory usage.

      from couchbase.cluster import Cluster, ClusterOptions
      		 
      from couchbase.auth import PasswordAuthenticator
      		 
      cluster = Cluster('couchbase://some-cluster?enable_tracing=false', ClusterOptions(PasswordAuthenticator('xxx', 'xxx')))
      		 
       
      		 
      cb = cluster.bucket('xxx')
      		 
      cb_coll_default = cb.default_collection()
      		 
      cb_coll_default.upsert(str(123), '123')
      		 
      for i in range(10000000):
      		 
        try:
      		 
          cb_coll_default.get(str(123))
      		 
        except Exception:
      		 
          pass
