2821, IOS content filter-BUG? HTTP CORE process eating router alive

HTTP CORE process in IOS router is causing network outage. Its 2821, zone based firewall with IOS content filter. IOS content filter was working fine for last month, all of the sudden today it is working faulty. Network is waving on and off with CPU being hogged. Tried reboot and problem returns. Any advice out there?

IOS versions below

Re: 2821, IOS content filter-BUG? HTTP CORE process eating route

Try moving to 12.4(20)T2 like me

Some issues have been corrected like object-groups for acls.

I noticed all has not been solved, but it is quite better.

On 12.4(22)T, I had memory fragmentation and overflow when I was issuing a lot of acl and object groups commands
