Hi All,
Intermittently(Data displaying fine and in a 2 or 3 minutes getting error. Again after 2minutes data were displaying.) i am getting the below error in site home publishing page. This data form is located in page layout.
"Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Microsoft SharePoint Foundation-compatible HTML editor such as Microsoft SharePoint Designer. If the problem persists, contact your Web server administrator."
This form has been working for months without any issues. I am thinking that some changes done in our third party data source or third party data source network issues.
I checked with Logs, but i could not understand what is the issue.

above logs i found in ULS.
When i open that Page Layout in designer "Data Form Webpart " displays the error as below.
"The server returned a non-specific error when trying to get data from the data source. check the format and content of your query and try again. if the problem persists contact the server administrator."
Could anybody help me to find the error from above logs.
Thanks & Regards
