I'm running into a bit of a problem and I'm not seeing an out. I run several Drupal sites that work just fine (macgeekery.com and codepoetry.net among them) so I'm not new to this, but this one has me a bit confused.
I installed a fresh copy of 4.6.4 on a brand new Linux 2.6 server running:
Apache 2.0.54 PHP 5.0.5 MySQL 5.0.16
The very first page loads without issue after I turn on caching. The next load of that page as an anonymous user, coming from the cache I would suppose, gives me a white screen with no errors in the Apache error log (and a 200 in the access). In the watchdog log I get the famed error:
Duplicate entry 'http://triton.codepoetry.net/' for key 1 query: INSERT INTO cache (cid, data, created, expire, headers) VALUES ('http://triton.codepoetry.net/', '
I searched Google and drupal.org and got a *lot* of hits ... and read them all. This incarnation, however, isn't a race condition as older forum posts would indicate ... this is every single page hit to a cached page.
If I turn off caching then the site works as expected, logged in or anonymous.
Now, CP and MG are run from MySQL 4.1, so is it possible some SQL behavior changed in-between that Drupal doesn't like? Is anyone using MySQL 5 with caching and no errors?
Thanks for anything you have...
