basically when clicking on the photo album from a members profile will produce the url "/{url}" instead of "/m/photos/view/..."
the problem is site wide after upgrading to 7.2.1. if i clear the catch it resolves for a while before it comes back.
this has become a serious issues for us since we serve around 120 pages per second from our server from 5am to 2am. its annoying because we had to cron job clear catch / restart apache every 5 minutes and kill all our accelerators increasing our server load majorly to bandage the problem while our team tracks iit down.
setup: ubuntu 14.04 / php 5.5.9 / mysql 5.5.44 / apache 2.4.7 / AMD 6376x2 (32cores), 64GB Ram
