Re: Strange lockup - using curl

Hi, I am facing a strange problem. I have a script that runs fine in one server but simply locks up in another. I´ve managed to find that when the curl_exec is called the problem appears, so I decided to use a sample script with the same example found at ww.php.net and got the same results. The server-status shows me SrvPIDAccMCPU SSReqConnChildSlotClientVHostRequest *0-0*201700/2/2*W* 0.00 27800.00.030.03 201.51.28.217myhost.comGET /temp/curl.php HTTP/1.1 I used strace with the pid shown # strace -p 20170 Process 20170 attached - interrupt to quit select(1589, [], [], NULL, {0, 685000}) = 0 (Timeout) gettimeofday({1150235209, 865596}, NULL) = 0 gettimeofday({1150235209, 866753}, NULL) = 0

The script. <?php $ch = curl_init(); // set URL and other appropriate options curl_setopt($ch, CURLOPT_URL, "http://www.myhost.com/"); curl_setopt($ch, CURLOPT_HEADER, 0); // grab URL and pass it to the browser curl_exec($ch); // close curl resource, and free up system resources curl_close($ch); ?>

You might need to compile php with --with-debug and see what you get back from an strace then.. the php-internals list would need to see the debug symbols to work out where it's breaking (and you'll need to talk to the -internals list). -- Postgresql & php tutorials http://www.designmagick.com/
