WebToLeadForm is creating records in ZOHO intermittently

Hi guys

Our website has various forms on it. When a user submits a form their details are added to the leads screen within Zoho. We've recently updated to the Enterprise package. Since then (and it may be a coincidence) some leads from our web forms dont get inserted into Zoho. Theres no pattern, it seems to happen randomly.

Has anyone else experienced this?

I have a CURLOPT_CONNECTTIMEOUT of 30.  Perhaps I should increase this? As I say - theres no apparent pattern to which leads dont get inserted into Zoho.

Im using php/wordpress/gravity forms

Thanks
