I have a set of 3 Cisco 6509 routers acting as my border routers, each with a BGP session to a different provider.  I filter the BGP table coming in from each provider to not send me routes anything smaller than a /24 due to my memory constraints on a SUP720PFC3A.  this works great.  However, last night, I accidentally took the filter off one of my peers, and it filled up the TCAM Utilization to 100%.  I quickly applied the filter, and reset my peering session and the usage then went back down to 40-50%.  HOWEVER.  I still get messages in syslog about the tcam overflow, and i am having some throughput issues globally, and packet loss on my loopback interfaces.  how do i clear the memory problem short of rebooting the chassis?  
(i have had this issue before, and rebooting the chassis fixed the issue, but i dont really want to do that)  attached is a file with some helpful info.  6509-1.txt
