Compressed transfers exceed the transferable record length

Question

When I execute a compressed transfer, I get an error message saying that the record length exceeds the transferable record length.
What could be the cause?

Answer

If a file with poor compression efficiency is transferred with setting DEFLATE Level as Best Compression, the record length of the file may exceed the transferable record length.

Control information records is added to the compressed file.
Therefore, if the original file size is very close to the upper limit of the transferable record length, and if the compression efficiency of the file is poor, that error will likely occur.

The error can be prevented by transferring the data without compression.
