Bug description

Upload a file, say 400 MB. After upload progress bar completes, there is a Processing files step. After a minute or so, there is this error message Error when assembling chunks, status code 504 . Eventually, the file is uploaded and would show up in the web interface, yet, there is this error. Depending on the size of the file, clamscan takes 100% of the CPU. Doesnt occur with smaller files say few MBs.

Steps to reproduce

1. Upload a file, say 400 MB and wait the upload progress bar completes,
2. Wait for the Processing files step
3. After a minute or so, there is this error message Error when assembling chunks, status code 504
4. Although the error message, the file is uploaded eventually after several minutes, depending on the file size. During this period all CPU time is taken by clamav

Expected behavior

No error message.
