After my host enabled suPHP, a previously working script has been timing out after ~3min (it varies, but the script has not run for more then 3, AFAIK).
The odd part is, the script is not throwing any errors that I can see (and yes, full PHP error reporting/logging is enabled and all MYSQL queries have been checked for errors, also) it simply stops. Refreshing the page will load more of the data the script is supposed to process (probably because the MYSQL queries have been cached...), but if there is a lot of data to process it never fully executes. The other oddity is that I can run test scripts for over 10 minutes on the same host w/ set_time_limit(0); / etc.

Başkasının bu başa, ya da zaman aşımı ve nasıl düzeltebilirim (assuming that dropping suPHP is not an option) neden olduğunu bilmek gerekiyordu. Orada 5.3.x PHP 5.2.x eşzamanlı güncelleme da oldu, ama ben bu soruna neden olduğunu şüpheliyim. :/
