We have problems running dCEF more often than CEF alone. Lots of old VIPs
with 32 MB RAM and a large Adj/FIB causes problems. This happens most on
routers with > 500 IDBs in use and/or a large ARP cache (> 5000 entries). I
agree that 128MB will not last for long. Also, the 7206 NPE uses
particle-based memory, which appears slightly more efficient than the RSP
system in terms of fragmentation management. Perform a show proc mem and
look for the amount of memory being held by *dead* processes. If this
number is over 10MB, you should reboot.
