Bug #17754: Unable to fork error in exec()

From: renzanl@yahoo.com Operating system: WinXP PHP version: 4.2.1 PHP Bug Type: Unknown/Other Function Bug description: Unable to fork error in exec() I get an 'Unable to fork' error whenever I use any of the program execution functions. <?php exec("c:\inetpub\wwwroot\gp\gnuplot.exe plot.data"); ?> Reports: 'Unable to fork [c:\inetpub\wwwroot\gp\gnuplot.exe plot.data]' But it is right, right? Im running IIS 5.1 under WinXP and PHP 4.2.1 in ISAPI mode. I saw some other bug reports dealing with this problem, but they claim that it was fixed in 4.0.6/7. -- Edit bug report at http://bugs.php.net/?id=17754&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=17754&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=17754&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=17754&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=17754&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=17754&r=support Expected behavior: http://bugs.php.net/fix.php?id=17754&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=17754&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=17754&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=17754&r=globals
