[wp-hackers] 500 Internal server error due to PHP APC?

[Ryan Chan]

Hello,

I have just moved my Wordpress to UBuntu 10.04 LTS, using the default
Apache / PHP/ APC.

I found that if I enable APC, Wordpress will die randomly after some
visits - It is okay when I restarted my Apache and just after some
visits, blank screen will be shown.

When I added "php_flag apc.cache_by_default Off" in the .htaccess,
problems solved, so this is due to Wordpress and APC?

Any idea to solve?

Thanks.
