Note The shared temporary files are located in the BizTalk host service account temp folder.
Temporary files may remain locked when connection pooling is used. The temporary files contain directory listings and SFTP server operations. They can grow large quickly if there are many files that are listed in the polled SFTP receive location folder. Additionally, if the host eventually restarts or crashes, these files may become orphaned.

Note This fix adds a new setting “Maximum Connection Reuse Time” in SFTP adapter, which will limit WinSCP connection life span. After Maximum Connection Reuse Time, connection will be closed and temporary files held by the underlying WinSCP session will be released or deleted.
