NAS Process: High CPU Usage

[Brayan Uzcategui]

Hello everyone,  

The NAS probe has recently been showing high CPU usage following the update to DX UIM Server 23.4.7.

Has anyone else experienced a similar issue?

Could this resource limitation affect the probe's proper functioning, such as with alert profiles?

I'm sharing some evidence with you

First, from the couple screen shots, you system is well under minimum spec. Not that that is the cause of your issue but something to keep in mind.

From the lack of other supporting information, I'm going to assume that you're new to the product - please forgive any simplistic sounding suggestions.

As a starting point, have you tried increasing the log level of the nas log? Level 5 is going to be noisy but it's going to tell you what's going on

Alternatively, you can connect Dr. Nimbus to this and listen to the message bus.

You have one core pegged which implies that this is not generic nas activity but related to a single task/thread.

The likely cause, since AO profiles are sequential, of that is a nas profile that's set to "on arrival" and it's updating an alarm which causes it to be placed back on the message bus and processed again. If it matches that profile again, you create an infinite loop that is never satisfied.
