Was this solved? I’m running mongod on a synology NAS/server and only write to the database, about, once per day. In the background, mongodb/WTCheck.tThread seems to write information out to disk every 60 seconds and I see the following getting logged to stdout at the same time.
“ctx”:“WTCheckpointThread”, “msg”:“WiredTiger message”
As a result my NAS never goes to sleep and is constantly writing or backing up those writes.
