ACS 5.2 - High memory utilization

[rhub]

Good morning everybody

I'm running ACS 5.2.0.26. Since some times I have a extremely high memory utilization of about 86%. The latency of RADIUS responses is between 10 to 12 ms.

Is this utilization factor normal behaviour ? If NO, what could be reason for it ? Which is the important log for such kind of possible problems ?

Best regards

I'm thinking about 2 things :

-network traffic (maybe it's being hit by ARP or broadcast storm ?). Take a wireshark capture and see fi there's any traffic not meant for the ACS that is there.

-Amount of authentication per second. Maybe there's a device sending 1 trillion authentication request per second ? Check the AAA authentication logs for failed or passed auths.

And also : does a reboot of the ACS solves the load or it comes back quite quickly at 86% ? If it solves it for some time, it could be a memory leak or sth internal to ACS. If the load is directly back at 86%, I'm thinking about external factors.
