Bug #71209 [NEW]: php-cgi script hangs when started from php-fpm via system(), passthru() etc.

From: lameventanas at gmail dot com Operating system: Linux PHP version: 5.6.16 Package: Scripting Engine problem Bug Type: Bug Bug description:php-cgi script hangs when started from php-fpm via system(), passthru() etc. Description: ------------ My lighttpd server uses fastcgi to run php code. The php code starts an external program that happens to be a standalone php script (shebang: #!/usr/bin/php-cgi). The script hangs when started from a php-fpm process manager, but works fine when started from a php-cgi "process manager". Just to clarify, the process that hangs is the php-cgi which is interpreting the standalone script. If I replace this with a shellscript, everything works fine. Test script: --------------- test.php: <? header("Content-type: text/plain"); echo "Starting\n"; system("/var/www/htdocs/script.php"); echo "Finished\n"; ?> script.php: #!/usr/bin/php-cgi -q <? echo "Hello world!\n"; ?> Expected result: ---------------- No hangs. -- Edit bug report at https://bugs.php.net/bug.php?id=71209&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=71209&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=71209&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=71209&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=71209&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=71209&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=71209&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=71209&r=needscript Try newer version: https://bugs.php.net/fix.php?id=71209&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=71209&r=support Expected behavior: https://bugs.php.net/fix.php?id=71209&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=71209&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=71209&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=71209&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=71209&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=71209&r=dst IIS Stability: https://bugs.php.net/fix.php?id=71209&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=71209&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=71209&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=71209&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=71209&r=mysqlcfg
