Salesforce can
send up to 100 requests inside 1 SOAP message. While sending this type
of Bulk Ooutbound message request my PHP script finishes executing but SF fails to accept the ACK used to clear the message queue
on the Salesforce side
of things. Looking at the Outbound message log (monitoring) I see all the messages in a pending state with the Delivery Failure Reason "java.net.SocketTimeoutException: Read timed out". If my script has finished execution, why do I get this error?
I have tried these methods to increase the execution time
on my server as I have no access
on the Salesforce side:
set_time_limit(0); // in the script
max_execution_time = 360 ; Maximum execution time
of each script, in seconds
max_input_time = 360 ; Maximum amount
of time each script may spend parsing request data
memory_limit = 32M ; Maximum amount
of memory a script may consume
I used the high settings just for testing.
Any thoughts as to why this is failing the ACK delivery back to Salesforce?
Here is some
of the code:
This is how I accept and
send the ACK file for the imcoming SOAP request
$data = 'php://input';
$content = file_get_contents($data);
if($content) {
respond('true');
} else {
respond('false');
}
The respond function
function respond($tf) {
$ACK = <<<ACK
<?xml version = "1.0" encoding = "utf-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<notifications xmlns="http://soap.sforce.com/2005/09/outbound">
<Ack>$tf</Ack>
</notifications>
</soapenv:Body>
</soapenv:Envelope>
ACK;
print trim($ACK);
}
These are in a generic script that I include into the script that uses the data for a specific workflow. I can process about 25 requests (That are in 1 SOAP response) but once I go over that I get the timeout error in the Salesforce queue. for 50 requests is usually takes my PHP script 86.77 seconds.
Could it be Apache? PHP?
I have also tested just accepting the 100 request SOAP response and just accepting and sending the ACK the queue clears out, so I know it's
on my side
of things.
I show no errors in the apache log, the script runs fine.
Thanks for any insight into this,
