[c-nsp] How to kill zombie administrative SSH session?

[Joann Deng]

By default only 5 ssh sessions are allowed in a single context FWSM. If type "show ssh sessions" it looks like no session is active. But if type "show resource usage resource ssh", see 5 current sessions:

FWSM1# show resource usage resource ssh
Resource              Current         Peak      Limit        Denied Context
SSH                         5            5          5           110 System
FWSM1#

Therefore can no longer access the FWSM via ssh. This is a bug, and can be fixed by upgrading. But is there a way to kill these zombie SSH sessions without upgrading the code or reboot FWSM?

The FWSM version is 2.3(4).

Thanks in advance,
