Hello,

Our customer is getting this error message:

What does this mean and how to solve it?
Thank you.

This looks like a false alarm. /tmp is just 10% used so it's ok to ignore the email.

OR

It may be possible that /tmp got full and you received an email and the temporary files got cleared off before you could look into it.

Thanks.
If they receive the email too frequently, is there an official way from CPanel to increase the size?
