Everytime I do a show run, wr mem or try to add a NAT statement, I get %NAT: System busy. Try later. I did the following but no luck:
%NAT: System busy. Try later
The %NAT: System busy. Try later error message appears when a show command related to NAT or a show running-config or write memory command is executed. This issue is due to the increase in the size of the NAT table. When the size of the NAT table increases, the router runs out of memory.
Reload the router in order to solve this issue. If the error message appears when HSRP SNAT is configured, configure these commands in order to resolve the issue:
Router(config)#standby delay minimum 20 reload 20
Router(config)#standby 2 preempt delay minimum 20 reload 20 sync 10
