FIX: File receive locations with alternate credentials get stuck in a tight loop after network failure

Consider the following scenario:

• You are using Microsoft BizTalk Server.
• You have multiple file receive locations (RL) that are pointing to different folders on the same Distributed File System (DFS) share.
• In order to access the share, the file receive locations have alternate credentials that are supplied in Authentication tab.
• In this scenario, if there is a temporary network issue that causes the RL to get disabled, BizTalk file receive host gets stuck in a tight loop where a single thread consumes the CPU.

• This may result in the application event logs receiving a high volume of errors like the following until the user manually stops the host instance:

This issue is fixed in the following cumulative updates for BizTalk Server:

Cumulative Update 2 for BizTalk Server 2016
