[c-nsp] 7500 having problems after upgrade from 12.0.19S2 to 12.0.31S1

[CLAEREBOUDT Elke]

This router was used for the peering at BNIX. We did shutdown the
ethernetinterface, so it has for the moment
3 ibgp neighbours (full bgp table)
1 ebgp neighbour (full bgp table)
1 ebgp neighbour (2 prefixes)

171815 network entries using 20274170 bytes of memory
858523 path entries using 44643196 bytes of memory
158768/31630 BGP path/bestpath attribute entries using 20957376 bytes of
memory
28498 BGP AS-PATH entries using 738336 bytes of memory
533 BGP community entries using 41518 bytes of memory
1 BGP extended community entries using 24 bytes of memory
0 BGP route-map cache entries using 0 bytes of memory
0 BGP filter-list cache entries using 0 bytes of memory
BGP using 86654620 total bytes of memory

The router ran fine for 2 years on 12.0.19S2.
We don't have exact stats on the memory usage with the old version.
I'm a bit worried because our other router is running low on memory also

Downgrade seems the most easy solution

What was your free mem under 12.0.19S2?  Assuming it was considerably 
more, I'd say there's bugs/memory leaks in the new IOS.  I've got
several 
RSP4's with full BGP routes and 40-50mb free, all running 12.2(18)S.
