    • Sprint 6 - towards CR1

      The camel sftp poller, during prePollCheck, is calling:

      isConnected = getOperations().sendNoop();

      which is in turn calling jsch:

      public synchronized boolean sendNoop() throws GenericFileOperationFailedException {
        if (isConnected()) {
            try {
                session.sendIgnore();
                return true;
            } catch (Exception e) {
                LOG.debug("SFTP session was closed. Ignoring this exception.", e);
                return false;
            }
        }
        return false;
    }

      On one SFTP server daemon (proftpd), this causes the server to close the connection and the polling stops.
