HTTP Error: cURL ERROR: 18

[GoogleCodeExporter]

What Salesforce.com Edition are you on? Enterprise

What PHP version are you running? 5.2.6-1+lenny2

What steps will reproduce the problem?
1. Create a Web2Contact form
2. Implement on website
3. Fill out information, click Submit

What is the expected output? What do you see instead?
Expect to be forwarded to return URL.

Instead receive error "ERROR creating the record"

No $create_record is passed back out all (even though SF object is created)

Traced error back to a "nusoapclient: Error: HTTP Error: cURL ERROR: 18: 
transfer closed with 
outstanding read data remaining" error

Please provide any additional information below.
This error doesn't constantly happen.  Perhaps one time out of ten the 
information will actually 
go through (like I said, though, regardless, the SF object is created).  The 
error came up out of 
nowhere, and the build date for our server's current PHP configuration is back 
in January, when 
we weren't getting this error at all.

I don't know SOAP all that well, but I did save the entire "$this" variable in 
salesforce.php, just so 
that I could trace it.  Here is the trace of when the error came up:

Any thoughts?  I implemented a workaround, where I eliminate the 
"$create_record[ 'success' ] 
== 'true'" check in w2s_engine.php, but I would rather find the root of the 
issue.

Please tell me if you need any more information from me on this error.

Thanks!

Hi, sorry for the late reply, this is a nasty one, not sure yet if the issue is 
with
the server or the nusoap script. Will try to investigate this further and 
update you
then.
