Kworker using up CPU

    Hello All,

    We are facing this issue since two days on our server. Kworker is using up most of the CPU and our CPU usage is going to 100%. While the traffic on our site is high and the CPU is always having a load but our site was running all fine, however, this is the first time we are seeing 'kworker' on top of CPU usage and whenever it shows up, our site goes down.

    Please check TOP screenshot -

    Can anybody help why this is happening and what could be the solution?

    Trophy Points:
    There are more hardware monitoring tools for view CPU status.You can monitor CPU uses per services and per process.
    Using vmstat ,iostat and ps tools ,configure appropriate command for appropriate result.
    #ps -mo THREAD
    ## ps -ef | egrep -v "STIME|$LOGNAME" | sort +3 -r | head -n 15
    #ps -lmo THREAD -p PidID
    #ps au
    Code (markup):
    Use mentioned command to your terminal and try to trace you issue.Those are not enough command ,but it can trace your issue a little.
