Description

I'm playing with Gitea on an AWS t2.micro instance (1G RAM) and running into memory issues. I attempted to push a moderate size repo up and it failed like so:

$ git push gitea Dev
Username for 'http://x.x.x.x': porjo
Password for 'http://[email protected]':

error: RPC failed; result=22, HTTP code = 500
fatal: The remote end hung up unexpectedly
fatal: The remote end hung up unexpectedly
Everything up-to-date
$ 

(the repo I was pushing is a total of 384MB on disk (including .git folder).)

Now when I use the Gitea web frontend I keep getting error 500 messages, and the Gitea console log keeps display 'cannot allocate memory' errors. e.g. I attempt to create a new repository via the web frontend, and see this is in the log file:

Top shows Gitea consuming in excess of 400MB!

I can understand why it might get upset about the initial push, but I would expect it to fail more gracefully. Why would it a) continue to consume so much memory b) not be able to allocate more memory for a simple operation (create repo) when there is still 210MB free!?

I've stopped and started Gitea and it has returned to normal. Attempting to push the same repo again causes the same issue.
