Camel ftp polling consumes file immediately before waiting for write is finished

Issue

• when we try to put some large size (ex. 5 mb), camel immediately consumes without waiting for writing process is finished.

• our env:

  • fuse 7.5 (Spring boot) app running on ocp 4.4
  • ftp server implementation using vsftpd dedicated vm outside ocp cluster

• How do we setup ftp pool listener on camel route to waiting for writing process is finished first before consume that file?
