[c-nsp] Static Default route missing

[Methsri Wickramarathna]

Hi all,
Yesterday we had a strange behavior on one of our Cisco 1841 router. Which
was suddenly unreachable and after when we troubleshoot the issue and found
out router has missing it's default-route. Initially we thought that
someone may accidentally removed it. TAC logs enabled on router so I have
went through all the logs and found no record regarding route removed.

We are taking router backups daily so I have compared previous router
backups and found out, default route was there on 12th November and missing
it on 13th November 2013.

Any idea about this issue.

Router IOS :- c1841-adventerprisek9-mz.150-1.M4.3.bin
