What IOS version?  If it's recent, like 12.2SX*, you don't have enough 
RAM.  Regardless, that seems to be what the maloc fails are saying.  On a 
6509 Sup2 with not quite 2 full views, and 512mb RAM, I have 212390720 
free.  If I had 256MB less RAM, I'd be in trouble.

You might want to open a TAC case on that.  My experience with other 
ciscos, BGP, full tables, and insufficient RAM, is that the session resets 
and then tries again.  It shouldn't be crashing/rebooting just because it 
ran out of memory.
