SFTP adapter sending data not work stable

Hi guys，

I used the SFTP adapter to send data to SFTP server.

When we test it with several thousand records, got a strange problem, that is:

after message mapping, I could see the file content is well; however, the file content is not correct

in the target sftp server, about every one thousand records, generating one line of unreadable record.

Would you like to help me out?
