user warning: Error writing file '/tmp/MYslVK3a' (Errcode: 28) query: SELECT COUNT(path) AS hits, path, MAX(title) AS title, AVG

Hi Folks,

I'm having this error trying to check the report of the most visited pages:

---------
user warning: Error writing file '/tmp/MYslVK3a' (Errcode: 28) query: SELECT COUNT(path) AS hits, path, MAX(title) AS title, AVG(timer) AS average_time, SUM(timer) AS total_time FROM accesslog GROUP BY path ORDER BY hits DESC LIMIT 0, 30 in /home/modules/statistics/statistics.admin.inc on line 56.
---------

Any thoughts? Thanks in advance!
