Hi All,
AIX, mySAP 6.0.3 connector, SAP R3 system

I am using mySAP.com connector to connect between SAP & WBI MB5

Yesterday, I got 10 messages in the fault queue of connector & saw polling function of connector was down (from connector trace). I restarted the connector & reprocess all the fault message by putting messages into connector request queue. Afterwards, everything is working fine. But I could not understand why polling function down.
I got the following from connector log --
Quote:
[Mesg: JCORfcException : com.sap.mw.jco.JCO$Exception: (104) RFC_ERROR_SYSTEM_FAILURE: connection closed without message (CM_NO_DATA_RECEIVED).]
[Mesg: Connection from SAPConnector to the Application is lost! Please enter 'q' to stop the connector, then restart it after the problem is fixed.]
Application state is disconnected]


FYI, my JCO version is 2.1.5

Quote:
From connector trace I got the following error --
[Mesg: :Error in AgentBOM.DoVerbFor - rtnObj.status = 4 rtnObj.message = Connection to SAP lost.]


I am using trace level 3 in connector as this is for production server.

After that as retrycount is 3, connector was started but polling function was down afterwards.

Does anyone know why connection closed & why polling function down after auto restart of connector?

What is CM_NO_DATA_RECEIVED?
