Please answer these questions before submitting your issue. Thanks!
What version of Scylla or Cassandra are you using?
Scylla Enterprise 2022.1.0
What version of Gocql are you using?
github.com/scylladb/gocql v1.5.1-0.20210906110332-fb22d64efc33
What version of Go are you using?
go1.19
What did you do?
Added credentials to scylla manager so that the healthcheck service uses SingleHostExecutor() that executes simple CQL query SELECT now() FROM system.local
on the node.
Afterwards, manager closes the connection with Close() method.
What did you expect to see?
I expect to see that the connection is closed.
What did you see instead?
I see that connection leaks and manager keep increasing number of opened connections to the node.

If you are having connectivity related issues please share the following additional information
Describe your Cassandra cluster
please provide the following information
- output of
nodetool status
- output of
SELECT peer, rpc_address FROM system.peers
- rebuild your application with the
gocql_debug
tag and post the output
Did you try with newer Go driver version?
I didn't manage to reproduce it locally even with the driver that manager is currently using.
Local env doesn't include TLS.
I'll try with cloud deployment and will observe its behavior in time.
