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;
eem ed syslog
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"
