R77.20.81 build 541 high CPU usage

Just to let you know that today I tried this build and it caused high CPU usage for no apparent reason. I event tried disable all non essential blades and load did not go away.

So, if you are going to try it heads up on this. If you experience the same drop a note here please.

Hi Hristo,

Did you notice that behavior on centrally managed or locally managed?

Hello Tomohiro,

It is centrally managed 1470 appliance.

Hi Hristo,

Thank you for the info.

I was wondering about the impact since we mainly handle lots of locally managed devices, and recently engaging with some customers to upgrade to this version. I will keep an eye on both scenarios too

Have the previous build ready in case you need to revert back. I think problem will exist on locally managed devices as well. What I noticed is that here 'top' complains about "unknown HZ value" on startup which kind of explains why appliance is so slow

Did you see the same behavior in build 525?

No, build 525 is rock stable here. No CPU or memory consumption issues.

Btw I was impressed by the beating it took last week when I tried HTTPS Inspection. Memory and CPU went sky rocket but it did not crash. Remarkable achievement
