I don't know this warning should or not affect long-term operation.
I think it might be related to this issues etcd-io/etcd#9911 . the man report server memory highly load due to too many connections.
Hi,
This is not an error we've come across before, but it sounds like it might be an issue with etcd/etcd client internals.
I found this blog post which seems to be written by someone who had a similar issue and looked into what was causing it, perhaps it may give some insight:
