Hi,

we have suddenly started to get the following message from our CSS? Does it mean what it states by the fact we are running on low memory? can anyone shed some light on this for us please?

ALERT ID = 0000AK5

TIME = Thu 13-Mar-2008 15:34:49 GMT

STATUS = Active

SEVERITY = Critical

MANAGED OBJECT TYPE = Content Networking

EVENT DESCRIPTION MEM-ocslb01.ybs.com/1.1

[SCM]:InsufficientFreeMemory;

CUSTOMER IDENTIFICATION = All

I have this problem too.

That looks like a snmp monitoring device reporting a problem with SCM low on memory.

You should check on the CSS itself, with the command "sho system-resources" and 'flow stat'

Hi Giles,

Thanks for your reply for the system resources looks okay its obviously something we need to look at when the event happens.

When we do the flow stat command

this is the output;

----------------------------------------------------

AGGREGATE FLOW STATISTICS PER-SP

Flow Manager Statistics - Slot 1, Subslot 1:

# 1/1 1920 253613467 1920 0

# 1/2 0 305 0 0

why is 1/1 heavy used and not 1/2? can you explain why this would be?

this info just indicates on which interface traffic is coming in.

You can check the total flow per/sec for each slot.

That's how the traffic is distributed between the modules.
