Cannot list directory error from SFTP route

Hi All,

I'm using camel 2.13.0 for doing an SFTP file transfer. Camel works fine
with downloading and uploading the files. But occasionally I get the
following error. Can someone be able to help on this? Appreciate your help.

EXCEPTION:
Cannot list directory: XXXX
