CISCO871 Running out of memory

[kajo_cisco]

Hello,

A couple of days ago, suddenly my internet connection went down. I was not able to ping or access the router via telnet and ssh. The switch in my room showed a light of the port to the router, so the port on the router must be up.

I reset the modem (last 4 line of the log) and it all started to wordk again.

I accessed the router and found the following messages:

I hope anyone can help me out. I am understanding that the router is running out of memory. But what is the reason? Has the logging buffer became too large? What can i do about it?

How do you route to the Internet?  I.e. do you have a static that routes to the interface or a static to the IP of the next hop?  If the former, try changing it to the latter.  The former, for Internet access, can fill all RAM with the ARP table.

I have a static route to the WAN interface (FastEthernet4). I get dynamic ip adrresses from my ISP so i can't set a static route to the next hop ip (or am i wrong now?)

hi kajo,

kindly unshut unused router interfaces and monitor again using the show memory command. if problem persist, contact TAC.

See if your router will accept "ip route 0.0.0.0 0.0.0.0 dhcp".
