Cpanel service and upcp failure

Kah Leong Chan

Hello all 

After a random spike to 100% CPU usage on almalinux 9, the cpanel service has failed. Everytime i try to restart the service i get 

cpanel.service: Main process exited, code=exited, status=2/INVALIDARGUMENT

when i try to run /scripts/upcp -- force i get this message: 

Stale PID file '/var/run/upcp.pid' (pid=15504)
Cpanel::Exception::IO::FileReadError/(XID 3apuha) The system failed to read from                                          the file “/proc/17560/stat” because of an error: No such file or directory

Any help would be appreciated!

    Kah Leong Chan,

    It is a common issue after a system crash or resource spike that leaves cPanel in an inconsistent state. There would be state PID files and processes that need removed.

    Please follow the below steps and instructions.

    1)  Remove the state upcp PID file if there is anything

    rm -f /var/run/upcp.pid
    rm -f /var/run/cpanel/*


    2)  Kill state cPanel processes

    ps aux | grep -i cpanel
    ps aux | grep -i upcp

    #Kill any state processes (replace PID numbers)
    kill -9 <state_pid_number>

    3) Restart cPanel services
     
    systemctl restart cpanel

    # If that fails, try starting individual components
    /scripts/restartsrv_cpanel
    /scripts/restartsrv_httpd

    4)  Run force upcp
     
    /scripts/upcp --force

    Let us know if those works.

    Thank you

    You may want to perform a smart test on the server's disk to see if there are issues there. Do you see any messages in /var/log/messages on the machine?

    No I didn't see any relating to a failure of any kind. Just file or directory not found

    What is the output of "ls -ld /proc" on your machine?  I'm expecting similar to this:

    # ls -ld /proc
    dr-xr-xr-x 194 root root 0 Oct  8 12:02 /proc
