Error in RFC to FTP asynchronous scenario

Hi Experts,

I have created RFC to File(FTP) scenario in SAP PI 7.31 AEX(java only) server.

When I execute RFC in sender SAP server, it gives run-time error(dump) as "call to messaging system failed".

But it successfully creates text file in target FTP server.

In message monitoring I found 2 messages for this.

First has status 'Canceled' with below message log,

Second message has status as 'Log Version' with no message log and with below message details.

Please suggest/guide me how to rectify this run-time error.

Thanks,

Amit Patil
