I assume that the memory has been overloading, but why this happend?

I reloaded the router and now works fine. Can anybody helps me ? Thanks in advance!

I have this problem too.

This happens a lot with IOS, it's a class of bugs called "memory leak".

You best bet is to upgrade IOS and hope it has beed fixed.
