made a small change

[mrn]

We had a C831 running vpn which was working fine. Our ISP has changed there DNS so I made the change on our router

from

ip dhcp pool CLIENT
import all
network 1.1.1.1 255.255.0.0
default-router 1.1.5.1
dns-server 3.3.3.3 3.3.3.4
lease 0 2

to

ip dhcp pool CLIENT
import all
network 1.1.1.1 255.255.0.0
default-router 1.1.5.1
dns-server 4.4.4.4
lease 0 8

now the router runs for about an hour then I get a message No memory available. And when I sign onto the box and run show run nothing is returned. A reload is the only way to sort it out.

Regards Mike

Can you post complete config less any passwords?

Ok. I seem to have sort this out by extending the lease time to 0 12. Looks like it is connected to how the new DNS handles renews of I.P's
