Hi

looks like you have a memory leak  or could be caused by fragmentation from not enough memory, unfortunately you will probably need to reboot to clear it temporarily

You may want to look at an upgrade or check this doc for some pointers, you could run it by TAC as well just in case there is a known bug or check the ios release for your version on Cisco website for known caveats it may already be there
