SoapFault exception: [HTTP] Error Fetching http headers

Hello all,

I have written a little PHP script to monitor the active nodes in my pools.

This is for a BigIP LTM on version 10.2.2 Build 763.3 Final

The bulk of my iControl/SOAP code is below:

This file was previously saved to help conserve bandwidth and troubleshoot this issue

$wsdl2="/dev/shm/iControlPortal.LocalLB.PoolMember.xml";

create my connections

$client2 = new SoapClient($wsdl2,array('location'=>$location,'login'=>$username,'password'=>$password,'trace'=>1,'httpsocket'=>NULL,'connection_timeout' => 120));

my get the status of the pool. This is the ONLY call I'm making

$pool_list = array("mypoolname.com");

$stats=$client2->get_object_status($pool_list);

Inconsistently, I'm getting the below exception thrown back at me. I also have included the debug output from __getLastRequest()

SoapFault exception: [HTTP] Error Fetching http headers in /usr/local/nagios/libexec/check_f5_pools:68

Stack trace:

0 [internal function]: SoapClient->__doRequest('

1 /usr/local/nagios/libexec/check_f5_pools(68): SoapClient->__call('get_object_stat...', Array)

2 /usr/local/nagios/libexec/check_f5_pools(68): SoapClient->get_object_status(Array)

3 {main}

mypoolname.com

It works some of the time but fails almost just as consistently. Are there any settings on the F5 that I need to look at? Or any guidance on how to debug further would be greatly appreciated!!!
