Try using only CEF. I have seen similar problems in the past using dcef

Hi Robert,

Thanks for the info. We are running dCEF...routers show about 4% CPU
load and the following memory:


BR02#sh mem              
               Head   Total(b)    Used(b)    Free(b)  Lowest(b) Largest(b)
Processor  613AE340   247798976   106515996   141282980   140653360
134546752
     Fast  6138E340     131080      37240      93840      93840      93788


Also, we are not blocking 92 byte ICMP due to the traceroute problems on
customers networks...

Thanks

%% Low on memory; try again later

Did you enable CEF?
Are you dropping 92 byte ICMP packets where needed?
