We’ve been receiving email warnings about “Connections % of configured limit has gone above 80” for a couple hours this morning, but can’t identify anything we’re doing as the source of these extra connections. We have a hosted M10 cluster, AWS N. California, v4.4.16, with a Realm sync instance. Realm sync says there has been 23 requests in the last hour, so not a lot.
Looking at the realtime data, local.oplog.rs looks to be consuming the most cycles, followed by _realm_sync.history and _realm.sync.resume_tokens. Is this just a lot of sync activity? Or should I restart the sync?
We had a similar issue last week that just “resolved itself” after a few hours.
