High CPU usage and network errors on Lenovo Redfish interface
The Lenovo Redfish interface has high CPU usage and network errors on a Google Brya emulator. The root cause appears to be a combination of a frontend script and a backend process.
Steps to Reproduce
-
Log into the Lenovo Redfish interface.
-
Observe system and network logs for errors.
-
Attempt to navigate the interface or send an HTTP GET request to the Redfish API.

which results in heavy latency issues and network crashes...
The system logs show repeated CPU frequency and thread time errors, while network logs show TCP connection issues and unreachable destinations. This suggests a resource contention issue or a bug in the Redfish interface's handling of system resources.
The Redfish interface should operate smoothly without high CPU usage, network errors, or connection failures.
