Suddently got this database error messeg in phplist

So everything was working well and when I was trying to login to php list backoffice today I got this error message in the browser:
Database error 1 while doing query Can’t create/write to file ‘/tmp/#sql_210_0.MAI’ (Errcode: 28 “No space left on device”)

What I don’t understand, is this something that have to do with the server(hosting company) or sometihng that I can solve my self somehow?

Anyone with a solution to this would be appreciated.

It sounds like the hard drive on the server is full. sounds like the database writes some data in a /tmp directotry.

possible solutions are to delete some files on the server, making addtional space available ffor the /tmp directory. Another possible solution would be to reboot the server. (the idea is that rebooting sometimes clears the /tmp direcotry).

Ultimately, you should make sure the hard drive has about 20% free space for optimal computer speed.

That was exactly the case, and the hosting company took care of it.
Thank you for the answer.
