hi,
I get this message every morning,

Error: Disk full (/tmp/#sql_1a2838_1.MAI); waiting for someone to free some space… (errno: 28 “No space left on device”)

and then I have to restart MariaDB from the site.com:8090/serverstatus/services

screenshot of df -h command:

What kind of application you are hosting? Your /tmp me be made up of temporary session files from your web application?

I also had same problem, After several studies I have found this is happening because of gzip compression.

After that I’have turned off gzip compression using OpenLiteSpeed dashboard. Issue will be fix.

Use cloudflare for gzip compression (bolti).

I forgot openlitespeed admin access

How can i get back?
