Failed to write session data

Question

I received this message after long time of using the same application without programming changes:

Warning: Unknown(): write failed: No space left on device (28) in Unknown on line 0
Warning: Unknown(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0

I thought is servers problem, but these messages are not showing in every computer. Is this some sort of problem with settings? What can I do to fix this?

Answer 1

From Bytes.com

The filesystem containing /tmp is full. Your system administrator should fix this immediately - and if they haven't noticed you ought to question what level of support you're getting, since a lot of things will go horribly wrong if /tmp is full.
