ISR4000 free memory issue?

[robin99]

I just deployed several ISR 4351 routers using either IOS 154-3.S1 or 154-3.S2. Client SNMP server triggers alert for the router's free memory as show below (832) only. I am not sure if this is a problem or not because normally the router's free memory should be much higher that that.

I have rebooted the routers and also update IOS but the amount of free memory remains.

Can Cisco or anyone here tell me about this? Thanks

Can you please post the output to the command "sh proc cpu sorted | ex 0.00"?

Hi,

The requested outputs for two routers are:

They are NOT in production yet so only the management interface is UP. We are worry if this would cause problem once put in the production. Thanks

Checked with TAC and this is NOT a problem on ISR4000 series.
