NIOS CP Appliance with 100% CPU Usage

[#1]

Hello,

we have a cp appliance that stucks with 100% CPU usage even after a reboot. After some debugging we found several httpd processes running with about 20% CPU usage in SN status.

We found that the Grid Master needs about 30 seconds to answer a rest api call while the 100% CPU usage CP appliance needs about 8 seconds.

Does anyone have an idear what could be the root cause of the cpu usage? How is the cp appliance interacting with the Gridmanager? Is the CP appliance using rest api call threw the tunnel?

Best regards

Falk

You should contact Infoblox Support - https://support.infoblox.com

The GridMaster is the source of truth for the entire Grid.  The CP member will be updating the GM's database.   I suspect a high rate of API calls against the CP member.

Infoblox Support will be able to identify what is going on.  Please have a support bundle for the GM, and CP appliances.   I'd also suggest a traffic capture from both the GM and CP appliances if possible.

Hello,

it looks like we have found the reason.

Some rest api calls are searching for all records with an regex as the only filter.
