How exactly is exit() function working when in fastcgi mode? does it finish whole instance of php process in fastcgi pool or just ends current request and return process to te pool?

İkinci cevap ise - ne bu tür günlükleri neden olur:

Durumu '0 ile exit çağırarak sonlandırıldı (dinamik) server "/ php.fcgi" (pid 25113) ': FastCGI [uyarmak]

?
