Subject: Site Access Error

Hello Guys,

All of a sudden, I get the following error when accessing my drupal 7 site:

--------------------------------------------------
PDOException: SQLSTATE[HY000]: General error: 3 Error writing file &#039;/tmp/MYPTOPd7&#039; (Errcode: 28): SELECT * FROM {system} WHERE type = &#039;theme&#039; OR (type = &#039;module&#039; AND status = 1) ORDER BY weight ASC, name ASC; Array ( ) in system_list() (line 165 of /home/verdeinf/public_html/techspecialist/includes/module.inc).

Additional
Exception: theme() may not be called until all modules are loaded. in theme() (line 1002 of /home/verdeinf/public_html/techspecialist/includes/theme.inc)
-----------------------------------------------------

Any ideas on possible causes or remedies?

Thanks. Dammy
