From: matthew at crasxit dot net Operating system: Windows 2008 PHP version: 5.3.1 PHP Bug Type: cURL related Bug description: Curl causing high cpu usage Description: ------------ I'm having an issue with curl on windows with php. If i have curl enabled in php and i run php through command line i get an instant cpu spike... php.exe cpu jumps to about 20% then back down. when i disable curl it only jumps to about 2% it does this on non curl scripts. even if i run a blank php file or php -i it jumps to 20... however httpd.exe using apache2_2.dll seems to be fine (~2%) extensions loaded: curl (problem with curl, fine without) gd2 mbstring mysql mysqli openssl Reproduce code: --------------- any code -- Edit bug report at http://bugs.php.net/?id=50406&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50406&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50406&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50406&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50406&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50406&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50406&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50406&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50406&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50406&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50406&r=support Expected behavior: http://bugs.php.net/fix.php?id=50406&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50406&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50406&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50406&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50406&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50406&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50406&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50406&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50406&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50406&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50406&r=mysqlcfg
