I was not sure to what happened before https://github.com/RocketChat/Rocket.Chat/pull/21550/checks?check_run_id=2338185382#step:7:9

so I have updated with base branch so the CI runs again

[KevLehman]

It appears the same happened again 🤔 weird, but seems like the Mongo container won't start on 4.2

[KevLehman]

Maybe @geekgonecrazy can help us on this one 👀 since to me it's unlikely this is a changes-related issue 😬

[sampaiodiego]

maybe MongoDB 4.2 doesn't accept the other params we're using 🤔 like --noprealloc --smallfiles --replSet=rs0

I was also looking into other Actions:

• like this that have specific params for replica set (which can simplify our CI file) https://github.com/marketplace/actions/mongodb-in-github-actions
• this one already starts mongodb with password, which would be a good addition to our pipeline: https://github.com/marketplace/actions/setup-mongodb-with-password

but for this particular issue, my bet are on those additional params.

[KevLehman]

Yeah, it looks like those options are tied to the nmap engine, so probably the 4.2 doesn't know what to do with them.

[KevLehman]

As expected, removing the mmap flags worked 😬 since the flags were mostly "informative", what do you think about removing those flags at all?

[sampaiodiego]

I think that's fine =)
