12.2(18)S is kind of bleeding edge, having only been released a few days 
ago.  I'd suggest you try again with 12.2(14)S1.  It's been out a couple 
months and has been field tested by many more networks.

You're upgrading from 12.0S to 12.2S, right?  I suspect you'll find that 
155MB just isn't going to cut it for full routes.  12.2 code uses more 
memory.  I bet you were close to running out with 12.0 code.  Upgrade to 
256mb or take less than full routes.
