Memory-Problem on a 4500

[admin_2]

I have an Cisco 4500 which acts as a dlsw-peer.

There is a fr-connection to the other dlsw-peers and a tokenring which is connected to our cip-router.

I often have the problem that I loose a dlsw-peer.

after investigating buffers, memory I saw that i/o-memory is low at certain time and I also had the following message:

Apr 23 16:51:08.516: %SYS-2-MALLOCFAIL: Memory allocation of 4676 bytes failed f

rom 0x603AFAB0, alignment 0

You can see that there is only 1068 of I/O Memory.

I have enough memory installed on the router (32Mb) - but shared memory is only 4 MB.

How does the shared memory depend on i/o ?

So what can i do ??

4500 routers do not have shared DRAM between the I/O and the Process memory. They are seperate physical DRAM Chips. If you are having problems with your I/O memory, you might try and use 'show buffer' commands to see if you have any leaks in your IOS. If not, you might want to consider upgrading the I/O DRAM.
