I found some problems when I configured ip nat inside at FastEthernet0/1. Router 1841 will reboot and cannot do anything. After I console this router, I found many crash files, like this;

------------------------------------
Every crash file will be like this. It will finish at "ip nat inside".
IOS version: c1841-spservicesk9-mz.123-8.YG3.bin
Anyone know about this problem?
Ps. Now, I upgrade to a new version c1841-spservicesk9-mz.123-14.T5.bin, it works but I would like to know that what the problem is?
Thank you very much :-)
