WAF - activated Common threat filter kills uploads after 30sec/120MB

Question

Hi all, 
 I'm having trouble uploading various .iso files (>2.5GB) while "Common Threat Filter" is enabled in WAF. 
 - no error within reverseproxy.log 
 - no problems with a 860MB .tgz file. 
 - different browsers or client devices 
 Some ideas where to look? 
 thx
