Assuming the session is on vty 2, try this command:

Router#show tcp vty 2 | i Foreign
Foreign host: a.b.c.d, Foreign port: xxxxx

This will give you the tcp port of the session (xxxxx).  You can then find
out the TCB ID of this tcp session using the tcp port:

Router#show tcp brief | i xxxxx
0BF3AF80  192.168.1.1.22             a.b.c.d.xxxxx          ESTAB

With this ID, you can clear the raw TCP session:

Router#clear tcp tcb 0BF3AF80

You'll need to confirm whether you want to clear the session.

If this doesn't clear the session and stop the problem, then probably you
will need to reload the router.  I'd recommend doing this in a maintenance
window.  BTW, did you try removing the archive configuration to see if that
helped?
