CAUSE

This problem occurs because the value of the Polling Interval property of the receive location that is configured for an FTP site is less than the time that it takes to receive a large file.

RESOLUTION

To resolve this problem, set the Polling Interval property in the FTP Transport Properties dialog box to a longer duration. To do this, follow these steps:

In Microsoft Visual Studio .NET, open your BizTalk Server project.
On the View menu, click BizTalk Explorer.
In BizTalk Explorer, expand the Receive Ports collection, and then expand Receive Locations for the location that you have configured for the FTP transport type.
Right-click your receive location, and then click Edit. The Receive Location dialog box appears.
In the right pane, click the ellipsis button (...) next to Address (URI).
In the FTP Transport Properties dialog box, set the Interval property for polling to a larger number under Polling, and then click OK.
Click OK to close the Receive Port Properties dialog box.
