The test script below reports the same memory_get_usage()-value for the first 300 requests and a 25% increase after but top(1) reports the memory grows up to 100MB when the script is done. Uncommenting the resetting of CURLOPT_POSTFIELDS doesn't seem to help. Uncommenting the recreation of $ch prevents the memory from being leaked. Test script: --------------- <?php $ch = curl_init('http://some-domain.com/dump.html'); for($i = 0; 1000 > $i; $i++) { # $ch = curl_init('http://some-domain.com/dump.html'); $post = array(); $post['data'] = base64_encode(str_repeat(hash('sha256', uniqid()), 1000)); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $post); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_exec($ch); # curl_setopt($ch, CURLOPT_POSTFIELDS, ''); if($i % 100 == 0) { var_dump(memory_get_usage(true)); } } ?> ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63859&edit=1
