Edit report at https://bugs.php.net/bug.php?id=78103&edit=1 ID: 78103 Comment by: davesw dot z dot phpbug at spamgourmet dot com Reported by: hardaqa at gmail dot com Summary: Allocating ~2TB memory after PHP_FCGI_CHILDREN-th request Status: Open Type: Bug Package: CGI/CLI related Operating System: Windows 10 v1809 64bit PHP Version: 7.2.19 Block user comment: N Private report: N New Comment: I ran into the same issue, but using IIS with FastCGI. A few requests would work, and then all would fail with trying to allocate 7813304906544536728 bytes! Disabling opcache didn't help, reverting to 7.1.30 did (my ISP didn't offer 7.2.18 as an option to revert to).

PHP's using PHP_FCGI_CHILDREN to manage workers pool, opcache enabled. After n-th request (n = PHP_FCGI_CHILDREN) to test.php script, php throws "Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 2052604301400 bytes)" Does not occur with either opcache disabled, PHP_FCGI_CHILDREN=0 or 7.2.18 and other versions of php. Test script: --------------- # run.cmd SET PHP_FCGI_CHILDREN=4 php-cgi.exe -b 127.0.0.1:9000 # test.php <?php $i = 1; define('test' . $i, 'frewgfrwfrwfg43gt53hgt5ege5wqh4g5q4w'); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78103&edit=1
