Well, as I replied, we are running dual RSP-4s in each router. However, 
when you run RSP-4, DCEF, Bridge Groups, Vlan Tagging and HSRP, it gets 
really really tight. At one point, we had an alloc failure because the 
router needed 64k and couldn't get it! Our only option at that point was 
to reduce the total number of routes we're dealing with.... or replace the 
Cisco w/ something beefier...

I mean.. this just ticks me off! 

Mar 15 15:43:37: %SYS-2-MALLOCFAIL: Memory allocation of 65536 bytes 
failed from 0x40458EB0, alignment 8 
Pool: Processor  Free: 6697392  Cause: Memory fragmentation 
Alternate Pool: None  Free: 0  Cause: No Alternate pool

Sounds silly, but I believe much of these types of errors could be 
mitigated by more aggressive memory defragmentation techniques, but I 
doubt that Cisco is going to pay much more attention to the RSP-4 based 
IOS versions. I think we're finally getting pushed to the wall here, and 
we'll need to consider alternative options, because RSP-16s aren't 
reasonable options given that we'd need 4 of them, and it would cost the 
better part of someone's salary to get them!

Are there commands deep deep deep within the kung-fu of IOS that will 
allow you to tune memory parameters to make it a bit more aggressive? 
Other memory optimization techniques that I should be studying? I'm all 
ears...
