It looks like your bootflash doesn't have enough free space to write the 
crashinfo file.  <4k is not enough room.  crashinfo file sizes can vary 
greatly depending on everything from IOS revision to configuration, to 
what the router was doing at the time of the crash.  I've found them 
to typically be a few hundred kbytes each.  YMMV.

If you don't have the room on your bootflash, you can tell the router 
where to write the crashinfo files by using subsets of the "exception" 
configuration command, i.e. "exception crashinfo file disk0:filename" or 
something similar.

The errors above could point to a number of things - bad memory or a flaky 
NPE would not surprise me.
