We have been using cPanel and CSF on CentOS 7.9 for a long time with no issues. Load Averages are always <1
Due to CentOs being EOL, we are moving our installation to RHEL 7.9. There is not one but 2 instances (Load Balancing). Everything else is identical. WHM works first, but over time (few days after) it becomes a lot less responsive. Every day Load Averages go up by 10-20. Last time I checked all the numbers were around 150-160 range. I can see in the logs that these averages come to that point gradually. There is no one process pushing the server. As a matter of fact, top command in shell shows nothing special. As soon as I disable the CSF, these numbers start to come down. In an hour they are all like 0.01. I checked the CSF settings but I could not figure out why this is happening. In the logs I don't see anything alarming either. What other places I can check to find the possible cause of this? TIA.
