"Null response to FXP_REAL_PATH" on SSHFTPClient.keepAlive();

Question

I get the following exception when calling keepAlive on SSHFTPClient: java.io.IOException: Null response to FXP_REAL_PATH

This exception occurs randomly on calling keepAlive. In my application, if client is already connected then only call goes to keepAlive, on calling this method it hangs for sometime and throws above mentioned exception.

Can anyone help me why I am getting this exception?
