If the address falls within one of the ranges in the "show region" output,it implies that the router was accessing a valid memory location, but thehardware corresponding to that address did If a software configuration change has recently been made, and the router is in a booting loop, a software bug may be causing this issue.

Identify the Cause of the Reload If you do not power-cycle or manually reload the router, you can find the cause for the reload in the show version output, as shown Software Failure On 2600 and 3600 routers, the router's I/O memory is configurable as a percentage of the main memory.
