Hung Router

I looked in the archive and did not see anything closely relating to what I
am experiencing.
In the midst of configuring my lab, a router that I am not currently working
on will hang. I still receive log messages, but the console prompt
disappears. I would normally relate this to high CPU utilization, but I
only had frame-relay configured at the time and had not begun building
anything on top of it. When I reboot, the router will complete the boot
process, but will not give me a prompt. When I boot the router ignoring
NVRAM, the prompt comes back. This happened on all my routers connecting to
the frame relay switch (2522), three 2600s and one 2501. I had completed
the OSPF configuration on one router and when I went to configure its
neighbor, the router was hung. While I worked on that router, the other
neighboring routers hung. Again, the recovery process was the same.
Has anyone seen this before? Or have any suggestions?
 
Thanks in advance,
 
Jeff Colburn
