0.74.1 crashloop when uploading big file to channel (70MB)

[himpierre]

Description:

I was trying to upload a mp4 to a channel. During that process Rocketchat crashloops. It does not recover even after a restart of rocketchat. Had to restore from backup. Error message:

Server spec, particularly RAM?

Rocketchat runs on a virtual machine with 4GB of RAM. It does not seem the VM was running out of RAM. Is that what the error message says?

thanks and cheers

Looks similar (related maybe?) to my #13191.

[himpierre]

Yes it does. WebDAV integrations is enabled on my installation but not used in this case. I just hit the + and "Computer" to upload the file.

No it doesn't, but from experience it is always worth checking the basics. I've seen a lot of people running into this sort of issue with 'unable to upload large file' due to the use of underspecced VMs. Just trying to differentiate your issue from others.

Also note the recommended version of node is currently like 8.11.4 though again it is unlikely to make much difference in this instance. Just going through the basics again. Check the release notes to see.

Should i try to upload that file to https://open.rocket.chat?

[reetp]

They may have file limits on there.

See if a dev comes back to you here first.

It seems my bug is somewhat connected to the webdav setting. After I disabled webdav integration i'm able to upload that 70MB file.
