When I retrieved a file from a remote host, ftp aborted the transfer immediately.
ftp> get alertORCL.log
200 PORT command successful.
150 Opening data connection for alertORCL.log (3347200 bytes).
426 Transfer aborted. Data connection closed.
226 Abort successful
At last, I found the mount point of the local destination folder was full with 100%. I think we all know how to solve this, right?
