503 error everytime! — CyberPanel - WebHosting Control Panel for OpenLiteSpeed

503 error everytime!

I have Ubuntu LTS.

Every 2 hours or don't know when I get this error!

Also, my /tmp/ folder full of "ses_" something tmp files.

Is there any way to prevent 503 every time? I need to restart the server like:
systemctl restart lsws/lscpd.

Please help.


  • Does anyone have any solution?
  • 4 solutions

    1.Use a cronjob to clear /tmp periodically
    2.Find out if you are using any other PHP executable other than the lsphp of the version used on site ( usually happens when you add crons with /
    3.Find out why your PHP application is creating so many sessions
    4. Ask you provider to increase inode limit for /tmp on your VM
  • Can you please explain more how to do that?
  • increase /tmp

    service lsws stop
    service mariadb stop
    /var/tmp && umount /tmp
    rm /usr/.tempdisk
    dd if=/dev/zero of=/usr/.tempdisk bs=1M count=10240
    mkfs.ext4 /usr/.tempdisk
