This has happened 2 times so far, each time when the yahoo bot makes it first visit in the morning. When it happens, the site is dead and only way to get it back is to restart httpd.
[client 188.8.131.52] PHP Fatal error: Maximum execution time of 60 seconds exceeded in /home/site/public_html/wp-content/plugins/w3-total-cache/lib/W3/Cache/Apc.php on line 40
each time i bumped my php execution time by 30. it was 30 first, then 60 now it's 90.
All caching is via apc. anybody else noticed this?
