Hi,
I have upgraded OEL 7.1 to 7.9 and analyzed that the CPU load remains always more than 1.
The VM is installed on VMware and it was initially configured with 2 vCPU and 2GB memory.
while typing any command the server gets hang so I have identified the issue with RNGD was causing the issue, so I disabled it and also increased the CPU cores to four and memory to 4GB.
but still, the load is 1 and there isn't any daemon running on the server. comparing it with OEL 6, where an Oracle DB and ERP application is running and the load is less than 1.
Code:
13:31:28 up 2:38, 1 user, load average: 1.00, 1.01, 0.97
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
Is it a bug in OEL 7.x? how do I figure out the resource utilization?
There isn't any resource contention on physical hardware.
Code:
