Large CSS file Online Compression crashing Django

[distributedlock]

Today I was planning on switching from Foundation to Semantic UI. Semantic CSS file is huge compared to say bootstrap or foundation and so I tried to compress it via Online Compression, but Django crashed because compression was taking too long. I've circumvented this by using offline compression which still takes around 1-2 mins but it eventually works. I was wondering why this was happening when doing it during online compression. Also, is there a way to have successful online compression for large files without crashing django? I wasn't sure if this was a bug in the django-compressor itself or was because it was trying to compress a large file in the request/response cycle.

My compressor related settings:

# Django Compressor Settings
COMPRESS_ENABLED = True

COMPRESS_OUTPUT_DIR = ''

COMPRESS_CSS_FILTERS = [
     'compressor.filters.cssmin.CSSMinFilter',
     'compressor.filters.css_default.CssAbsoluteFilter',
]
COMPRESS_JS_FILTERS = [
     'compressor.filters.jsmin.JSMinFilter'
]

COMPRESS_OFFLINE = True
