PHP 4.0 Bug #5686: require and include randomly do not load pages

From: J.Antonio@jaruz.com Operating system: Win NT 4.0 Build 1381 Service Pack 6 PHP version: 4.0.1pl2 PHP Bug Type: Misbehaving function Bug description: require and include randomly do not load pages Hi. This bug is identical to bug # 4593 but I submitted it because it concerns the latest PHP build and a different OS. The problem is: while using PHP4 it will randomly do things like: ----------------- Fatal error: Failed opening required 'header.inc.php' (include_path='') in C:\precisa.gob.mx\wwwroot\jaruz\updates.php on line 3 ----------------- First the script it works fine. The error appears after maybe the 2nd or 3rd reload, and thereafter it will always give the error. Between the reloads, the scripts was NOT modified. There are also no error in the script. If I copy-paste the script and make a new .php file, it will work just fine at first, and after a few reloads it will give the same error. This error concerns requires and includes. The PHP setup is default. No php.ini file. Using as ISAPI module. Server is Microsoft-IIS/4.0.
