Random AFT Error - Server's host key does not match PuTTy

Hi,

We have a AFT FileTrans job which connects to a unix FTP server to transmit files. The job seems to fail at random returning the following error:

Unable to connect to SSH server: SFTP_Connect failed: WARNING - POTENTIAL SECURITY BREACH! The server's host key does not match the one PuTTy has cached. This means that either the server administrator has changed the host key or you have actually connected to another computer pretending to be the server. The new key fingerprint is:....
- Connection abandoned.

The error appears only at random. We have verified that the ftp server host key has not changed and the IP address has also been added to the Authorize Host utility under the Control M Agent - Configuration Management window. Also, the remote server does not exist in a cluster environment.

A non control M job process seems to connect and transmit files without any problems.

Any help/advice would be greatly appreciated.
Thanks in advance,
Yash
