  IP Network Routing? 
 The Question is:
 
Every now and then, the volatile (non permanent)routing table on our
 AlphaServer 800 5/500 seems to become corrupted. When this happens, if you try
 to access it ($ TCPIP show route), your session 'locks up' and eventually
 retuns with a virtual memory erro
r.
You are however, still able to access the Permanent routing table ($ TCPIP show
 route/perm).
The only way i have found to resolve this, is to re-boot the server.
 
Could you please explain what is happening, why, and what I can do to prevent it.
 
below is the memory details of this system.
 
Thanks
