seems related to RocketChat/Rocket.Chat#19082

can you please run with the following environment variable set and see if it helps?

yep this solved the high cpu issue, thanks!

[sampaiodiego]

good to know, thanks..

FYI there is a fox this already RocketChat/Rocket.Chat#19181

once that is merged we'll launch a 3.7.1 release so you won't need to env var anymore.

@sampaiodiego
Does this only fix "mmapv1 database engine or when no admin access was granted to the database user,"?
we use 3.3.3 version,and it will have a high cpu load sometimes,does this work for wiredTiger ?thank you.
