#39766 [NEW]: PHP wastes time on a slow network connection instead of recieving the buffers

From: deepak dot vasudevan at lavanyadeepak dot tk Operating system: Windows 2003/IIS 6.0 PHP version: 4.4.4 PHP Bug Type: CGI related Bug description: PHP wastes time on a slow network connection instead of recieving the buffers Description: ------------ I have configured PHP with IIS 6.0 in CGI flavor. I have also optimized the following values in PHP.INI to facilitate huge uploads to the tune of 200 MB: (*) Memory Limit (*) Max Input Time (*) Max Script Time The file upload passes fine if the client browser is connected to the web server in a high speed network. It works like a charm since it does not spike the CPU too. However, when I move the webserver to a different network and the access the server, because of network delays, even though Network Packet Analyzers show incoming data to the webserver running PHP, PHP does not do anything after 70% of the filesize. It sits silently and then after Max Input Time/Max script Time, gets recycled by IIS with the error message "CGI Misbehaved". All other settings are identical. Expected result: ---------------- PHP should behave identically in all environments. Slow network and CGI flavor seems to disturb the buffering strategy. Actual result: -------------- The php process gets killed by IIS with CGI Error "CGI application misbehaved ...". -- Edit bug report at http://bugs.php.net/?id=39766&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=39766&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=39766&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=39766&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=39766&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=39766&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=39766&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=39766&r=needscript Try newer version: http://bugs.php.net/fix.php?id=39766&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=39766&r=support Expected behavior: http://bugs.php.net/fix.php?id=39766&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=39766&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=39766&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=39766&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=39766&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=39766&r=dst IIS Stability: http://bugs.php.net/fix.php?id=39766&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=39766&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=39766&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=39766&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=39766&r=mysqlcfg
