"Enabled hello features" log line is being sent out almost once every millisecond

[dantinkakkar]

I think this is a rather intermittent issue that I'd seen earlier but now have confirmed that it exists:

A particular log line sometimes is thrown out repetitively to a great extent. We observed in one of our environments that this log has been sent over 46 million times in 15 hours (that's almost once per millisecond). This is what it looks like:

Enabled hello features: [SeqNo, Xattr, Xerror, SelectBucket, Snappy, Json, Duplex, UnorderedExec, Durations, AltRequests, SyncReplication, Collections, PreserveExpiry, CreateAsDeleted, ReplaceBodyWithXattr]

We are on 1.0.0-beta.1 right now. It is possible that the bug might be absent in later versions and we're updating but since we don't know how to reproduce it we can't tell whether this is actually fixed.

Happy to provide any additional details if needed.

Hi @dantinkakkar that line is logged when the SDK establishes a new connection to the kv server. So you're seeing it creating 46 million connections there. There have been bug related to connection storms which have been fixed such as 6ba442f , so I would think that the issue should go away if you upgrade.
