3845 Software Forced Crash

We have a 3845 router that has been running fine for quite some time.  All of a sudden the router is rebooting about every hour with the following message:

There seems to be some memory

There seems to be some memory block issues.  

 

This means that the OS isn't "returning" un-used memory back into the pool properly.  So the router keeps getting more memory until there's none left and crashed.  This can happen at anytime and is more true when the router has a very long up time.  

 

You may want to consider upgrading the IOS.
