RC stops responding after opening channels containing video files

Community Support

Issue:
Freshly created a docker instance of Rocketchat using v7.5.0 and Mongo 6.0
The original dump was exported on a snap installation of same version and imported into the Docker installation of RC.
I can log in just fine, updated SITE_URL (even though I have done that in the .env file already), I can switch channels and see Photos, and everything is working fine.
Until I switch to a channel containing video files. It doenst have to be large files, any size will guranteed produce this issue.
Then the RC server becomes unresponsive and I either have to wait 5 minutes or so, or need to restart it for some strange reason.
The docker container keeps running, doesnt restart on its own.
For this time the memory mongod takes up is 14.9GB and doesn’t grow, doesn’t use CPU cycles, it just sits there idling, more or less.

The host has 32GB of memory allocated. CPU is a i5-9500, system storage is SSD.

Do we need to wait like 10 minutes for video files to load, or what could be the culprit here?
I doubt adding an NVME, rather than a S-ATA SSD or allocating more memory would help here, would it?

Not really anywhere near enough info to tell (I’ve posted many time to to report issues effectively) but at a guess you probably haven’t read the docs and are still using GridFS.

Don’t.

After that check your reverse proxy, websockets, internet access, and look at the errors in your logs.

strange thing is that the chat is working fine on the source machine with the current settings.
I dont see a valid point in making my life even harder somehow migrating to “filesystem” rather than “GridFS”
also I do not have issues updating.

but thanks for attempting to help, I will switch to a snap installation, instead of docker.

I’d fix docker. Personally. I’d also imagine there are a few more issues you haven’t fixed yet but you have provided minimal info.

GridFS? Getting off it will make life easier.

You can ignore their recommendation, and mine, at your peril.

But make sure you mention you didn’t read the docs and take the advice when you find your system crawls to a halt. Which it will eventually.

Here you are from the docs, just to be crystal clear you know what you are ignoring.

I’ve emphasised the important bits for you.

By default, GridFS is used in Rocket.Chat for file storage because MongoDB offers this functionality with zero configuration.

However, it is not recommended for production environments due to the high load it places on the database.

GridFS can only be suitable if:

A retention policy is in place to manage file storage.

You are storing only a small number of lightweight files each week.
