Custom upload errors with large csv's

[sal-uva]

Large csv files either fail to upload or cause a timeout error with the custom upload option. I've gotten both these errors with ~1GB csv files:

Timeout when reading response headers from daemon process Truncated or oversized response headers received from daemon process

In some cases, the file will upload, but cause a timeout error. I've tried to add and increase header-buffer-size in the apache2 configuration (4cat.conf) but no results.

We should probably look into more sustainable and efficient ways of doing the file upload.
