EV_INGRESS_DATA during ST_HTTP_PREPEND_HEADERS

Hi all,

I am getting EV_INGRESS_DATA during ST_HTTP_PREPEND_HEADERS errors on a VIP I just created. When I remove the HTTP profile from the VIP it all works fine. We are running BIG-IP 10.2.2 Build 852.0 Hotfix HF1. The nodes on the backends are running IIS 8.5.

thanks in advance.
