SYS-2-MALLOCFAIL: Memory allocation

atala · ‎05-02-2006

Hello,

I have a cisco 2600 router with IOS version 12.3 (see below the ourput of show version).

I have two connections to the internet, the first one behing which I am doing NAT overload, and the second for my servers to be seing over Internet.

I am trying to implement routing using route-map, when I entered the "ip policy route-map" command on the incoming interface, after a while (about an hour), the router is blocking all packet and I no longer have connection to internet from both connection, I must reboot the router in order for it to come back up.

Hi

Do find the reason and also the recommended action to avoid the error msg..

Possible Reason :

The requested memory allocation is not available from the specified memory pool. The router memory has been exhausted or fragmented. This condition may be caused by the current system configuration, the network environment, or a software error.

Recommended Action:

If you suspect a software error, copy the error message exactly as it appears on the console or in the system log, contact your Cisco technical support representative, and provide the representative with the information you have gathered.Otherwise, you may need to add more memory or reduce the number of features you are trying to support.
