FTP Sender - Status stuck in "Processing Started"

Friends,

I have a Communication Channel Type "FTP Sender" which ends up crashing intermittently during the implementation of reading / conversion of data. The message reaches the status "Processing Started" and not out of it without displaying any error log.

When I go in the Integration Directory and the Active CC, he returned to work.

Has anyone been there who can help me?

Thanks.

Bruno
