I've been having this issue for about a month now and still don't have an answer. We recently attempted to replace our 515 running 6.3 with a new Asa5520 device. We use Websense for url filtering. We are now having major problems with overall internet slowness, downloads hanging, page timeouts things like that. Working with TAC, I have downloaded different versions of IOS, (currently running 7.04(12)) and the issue is still not resolved. I called Websense today and they said Cisco has a hotfix for this issue but did not know the hotfix# or link to download it. Has anyone heard of this problem before and does a hotfix exist? Help would be GREATLY appreciated.
