PHP - curl_exec hangs

Question

I am having a strange problem with the below php function. Unfortunately this is one of those special \"Production only\" case.

function requestPost($url, $data)         


        

Answer 1

add the following at the end your script to get the cause of failure

if( $rawresponse === false )
    syslog( LOG_INFO , "base.php::requestPost() : ".curl_error($curlSession) );

EDIT 1

It could be an internal problem of curl. Before all check all server runtimes are up to date ( php, php-curl and apache at least). Check all their logs..... Then I would recommand comparing results between several production environment or a dev/test environment.

Finally try to narrow down a minimal testcase that could reproduce your issue and publish full code for the test case.
