I'm trying to overwrite https://en.wikipedia.org/wiki/File:Jefferson_Davis_High_School_band_2020.ogv. Anything over 100MB is no bueno due to T278389. Anything under 100MB is no bueno either. I randomly get one of the following:
>Could not acquire lock for "mwstore://local-multiwrite/local-public/7/78/Jefferson_Davis_High_School_band_2020.ogv".
>Return to Main Page.
Or:
>Error
>Our servers are currently under maintenance or experiencing a technical problem. Please try again in a few minutes.
>See the error message at the bottom of this page for more information.
>Request from (my ip) via cp3052 frontend, Varnish XID 690378672
>Error: 503, Backend fetch failed at Thu, 22 Apr 2021 16:35:19 GMT
Or:

Edit: eventually one of the uploads made it through. Oddly, I found out because I got an upload warning for a duplicate file. So despite throwing an error, one of the uploads did succeed.
