#50553 [Bgs]: Multiple curl_exec and curl_close looses host

ID: 50553 Updated by: jani@php.net Reported By: levi_tedder at hotmail dot com Status: Bogus Bug Type: cURL related Operating System: Windows XP, Windows 2003 PHP Version: 5.2.12 New Comment: Whatever is happening happens in curl, so ask support there, not here. But basically what you're doing: Just DO NOT do that. If you need to do that, you're either doing something nasty or don't really know what you're doing.

But basically what you're doing: Just DO NOT do that. If you need to do that, you're either doing something nasty or don't really know what you're doing. ------------------------------------------------------------------------ [2009-12-22 08:00:48] levi_tedder at hotmail dot com Description: ------------ If you have a web server host that responds very quickly and you're doing a lot of requests on it, curl will eventually respond "couldn't connect to host". This happens on my Windows XP machine and Windows 2003 server, but I've been unable to reproduce on Windows 2008. If I add a delay with usleep(50000) it seems to be ok. I'm not sure if this is by design, OS-restriction or wrong usage (I've tried forums) or actual bug. Please forgive misplacement. To get the script below to exit with "couldn't connect to host" you need a fast responding web server host. Reproduce code: --------------- <?php $url = "http://www.example.com"; for ($i = 1; $i <= 6000; $i++) { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL,$url); curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); $result=curl_exec ($ch); if (curl_errno($ch)) { exit(curl_error($ch)); } else { curl_close($ch); echo "count: $i\n"; } } ?> Expected result: ---------------- count: 1 . . count: 6000 Actual result: -------------- count: 1 . . count 4322 couldn't connect to host ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50553&edit=1
