That bug was recently fixed (thanx, Tony): http://bugs.php.net/?id=32742 Previous Comments: ------------------------------------------------------------------------ [2005-05-18 16:08:05] joel at joelstrellner dot com I am having the exact same problem in version 5.0.4. I have narrowed it down to curl, but I can't narrow it down any further. I tried using CURLOPT_BUFFERSIZE to overcome it but I am not sure that it is even working. I am pretty sure that it has to do with curl_multi_init and the related multi functions. The exact same code using one connection at a time does not cause an error of any kind. the options I am giving it are: $conn[$i] = curl_init($url); curl_setopt ($conn[$i], CURLOPT_BUFFERSIZE, 8192000); curl_setopt ($conn[$i], CURLOPT_RETURNTRANSFER, 1); curl_setopt ($conn[$i], CURLOPT_URL, "$url"); curl_setopt ($conn[$i], CURLOPT_USERAGENT, $user_agent); if (($referer!=NULL) AND ($referer!='')) curl_setopt ($conn[$i], CURLOPT_REFERER, $referer); curl_setopt ($conn[$i], CURLOPT_CONNECTTIMEOUT, $connecttimeout); curl_setopt ($conn[$i], CURLOPT_TIMEOUT, $timeout); curl_setopt ($conn[$i], CURLOPT_HEADER, 0); curl_setopt ($conn[$i], CURLOPT_FOLLOWLOCATION, 1); curl_setopt ($conn[$i], CURLOPT_MAXREDIRS, 3); curl_setopt ($conn[$i], CURLOPT_FAILONERROR, 1); curl_setopt ($conn[$i], CURLOPT_ENCODING, ''); curl_setopt ($conn[$i], CURLOPT_COOKIEJAR,"cookie.txt"); curl_setopt ($conn[$i], CURLOPT_COOKIEFILE,"cookie.txt"); curl_setopt ($conn[$i], CURLOPT_FOLLOWLOCATION,TRUE); curl_setopt ($conn[$i], CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt ($conn[$i], CURLOPT_SSL_VERIFYHOST, 1); curl_multi_add_handle ($mh,$conn[$i]); the error I am getting is a seg fault (11) then the script stops executing. ------------------------------------------------------------------------ [2005-03-16 01:00:07] php-bugs at lists dot php dot net No feedback was provided for this bug for over a week, so it is being suspended automatically.
