InfoPath Dev

Hi All,

I have a simple infopath form published on sharepoint. All users are able to submit it to the sharepoint using this form, however, some users are getting below error message:

Infopath cannot submit the form.

the site may be offline, read-only, or otherwise unavailable.Unspecified error.

I checked permissions and all permissions have 'Approve' Permissions for this library. I know that the site is online because some other users submitted form a minute back to that  library. What could be the problem?Please help!

Thanks

 Hello,

 I also face the same issue.I accessed the above link, sorry - could not find any suitable solutions for me. Eg : User A submits form successfully many times.Sometimes when submitting , gets error message as (InfoPath cannot submit the form. An error occurred while the form was being submitted. The form cannot be submitted to the following location: http://<URL>
The site may be offline, read-only, or otherwise unavailable.The thread is already in background processing mode.) . This issue is also faced for some other users. When looking the file at SP library, it does not look like a valid XSN file. When clicking the file gets error message as

" The XML page cannot be displayed

Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.

XML document must have a top level element. Error processing resource '.................

Please note that this happens some time only.Rest of the time the same users can submit the form without any issue. We are using Infopath 2007  / SharePoint 2007.  Please help me out with a solution. Thanks.
