[Phpwiki-talk] phpwiki error message

[Dwayne H. <dho...@ha...>]

We have a php wiki set up.  It is running on a mysql database.  Has been 
working great with no problems until yesterday afternoon.  Now we get 
the following error message: 

Fatal PhpWiki Error
lib/WikiDB/backend/PearDB.php:778: Fatal[256]: wikidb_backend_mysql: 
fatal database error

DB Error: unknown error
(SELECT linkee.id as id, linkee.pagename as pagename, linkee.hits as 
hits, linkee.pagedata as pagedata FROM link, page AS linker, page AS 
linkee WHERE linkfrom=linker.id AND linkto=linkee.id AND 
linker.pagename='HomePage' ORDER BY linkee.pagename [nativecode=1 ** 
Can't create/write to file '/tmp/#sql445e_1033_0.MYI' (Errcode: 13)])

I googled and found other wiki's with the same problem but no fix.  Any 
help would be great.   We are using php version 4.3.4, and mysqld 
version 4.0.18, with a custom kernel 2.6.6.


thanks,
