Hi, My 3640 router has 128MB of RAM and I see that the available memory keeps getting smaller until the router stops working and I have to reboot. Could it be bad memory? Thanks.

1. You have a high CPU utilization but nothing indicates which process is causing it.
2. You have a high memory utilization for the following process;
chunk manager
ipsec keyengine
eem ed syslog
ssh process
If you don't use IPSEC VPN, use an IOS with no IPSEC feature.
Use telnet if you are connecting to the router from a secure site, use ACL in VTY instead of using SSH.
Monitor "chunk manager" if the memory utilization is increasing over time (hours or days)
Capture "show tech-support" before you reboot the router next time it has a memory problem again and post it here
Check if you have memory errors in the log like "SYS-2-MALLOCFAIL" and post it here together with the "show tech-support"

Can you post the following command outputs?
show version
show proc mem
show proc cpu

I'm going to downgrade the IOS and see happens. Thanks for your help.

make sure you are paired with Cisco Approved memory, and that the ICs on the modules as well as the SPD Serial Code on the PCB is correct on each. Here is a list of the parts:
