show route summary ?

I'm not totally familiar with the M20, but do you have multiple SSBs?  It 
really does sound like you're out of DRAM on the PFE/FEB (or maybe it is 
called SSB in the M20) and it's choking.  I'm pretty new to Juni's but I 
was also under the impression that heap and buffer use the same DRAM space, 
but apparently not (since yours adds up to more than 100%)
