Hey,

Your router IOS is quite old. This is happening because of an IOS defect : CSCsa68051

Use the following link to check more details about this bug:

http://tools.cisco.com/Support/BugToolKit/action.do?hdnAction=searchBugs

You would have to upgrade the IOS to 12.4 version to get a fix. Latest IOS available for your router is 12.4.25c.

You can refer to the following document for IOS upgrade procedure:

Nitpick: the above should say:

Latest 12.4 Mainline IOS available for your router is 12.4.25c.
