[BUG] Uploaded files buffer into memory instead of disk

[MikuAdministrator]

Bug Description

When large files are uploaded, all of it goes to memory instead of disk. If the server runs on less memory than the uploaded file, the whole system hangs and only a reboot can fix it.

Reproduction Steps

1. Set machine memory to some arbitrary amount like 1 GB
2. Upload a file larger than 1 GB like 2 GB.
3. Watch the memory fill up and eventually brick everything.

Expected Behavior

Uploaded files should get buffered in disk.

Actual Behavior

Uploaded files are buffered in memory, causing huge memory requirements for large files.
