> Hi All,
> I have an old (2004) Intel based server with 4G of ram running
> Linux ndgonline.net 2.6.18-92.1.22.el5 #1 SMP Tue Dec 16 12:03:43 EST
> 2008 i686 i686 i386 GNU/Linux
> fully up to date using centOS rpms for apache, php, and mysql.
> I have just changed from dmraid to md raid for the OS on mirrored 80Gb
> SATA drives. (long story for another time)
> Mysql lives on a Intel hardware raid 5 controlled array - as is has for
> four years.
> My application has not changed and also runs just fine on another server
> (although this one is 64 bit) that has a mirrored mysql database
> replication from this one.
> I have compared apache conf files, my.cnf and all appears well.
> The page that times out on our firefox browsers after 30 seconds does
> have a series of complex mysql queries.
> There are no log messages other than ssl_error_log that shows:
> PHP Fatal error:  Maximum execution time of 30 seconds exceeded in
> /var/www/htdocs/ndg/includes/customHandler.inc on line 87
> the line number varies as does the file name it reports.
> It will serve pages that only have a few records, yet on my functioning
> server even the large pages return over the internet in less than 2
> seconds.
> So I'm thinking not enough memory? - but it was working well last Monday.
> something slowing mysql?? - all other queries in this app appear just fine
> php having issues?
> How do I get some extra log info to track this down?

Did you do the obvious and check for table or index corruption?
