Linux – /tmp always gets full even after resize

centos5linuxtmp

I have a cPanel Server with 4GB of Ram and 4GB of /tmp space. I always get this error:

Will this cause slow performance? and can I delete everything?

Drive Critical: /tmp (/var/tmp) is 95% full

Drive Critical: /usr/tmpDSK (/tmp) is 95% full

Best Answer

No, you definitely can't delete everything in there. /tmp is where the system stores its temporary files when it's running.

What you can delete depends on what's running on the server.

I would recommend looking at the file list and finding out what's writing so much to your /tmp folder. ls -l and lsof will be helpful in that respect.

The ls -l command gives you a detailed list of the files contained in the directory, and lsof will tell you which files that the processes on your server have open.

If these items exceed your technical skillset, I'd recommend contacting your reseller account's technical support or contracting someone who can assist you further.
