[Former Member]

Hi I received strange kind of error..

Have anyone of you seen something like this before?

<SAP:AdditionalText>com.sap.engine.interfaces.messaging.api.exception.MessagingException: com.sap.aii.adapter.rfc.afcommunication.RfcAFWException: RfcAdapter: receiver channel has static errors: can not instantiate RfcPool caused by: com.sap.aii.adapter.rfc.RfcAdapterException: error initializing RfcClientPool:com.sap.aii.adapter.rfc.core.repository.RfcRepositoryException: can not connect to destination system due to: com.sap.mw.jco.JCO$Exception: (**) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=logon*.*.com GROUP=SPACE R3NAME=2 MSSERV=sapms2 PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR partner '.*..*:sapms*8' not reached TIME Sat Feb 11 20:37:58 201 RELEASE 710 COMPONENT NI (network interface) VERSION 39 RC -10 MODULE nixxi.cpp LINE 3147 DETAIL NiPConnect2: *.*..*:*** SYSTEM CALL connect ERRNO 79 ERRNO TEXT A remote host refused an attempted connect operation.

Hi,

1. is the connection from PI to the destination opened ? it looks like a typical connection error where systems don't see each other (can you try IP instead of name server)

2. can you please use ABAP proxy instead of RFC adapter ?

Hi,

MSHOST=logon**.*.com is name server, but it can be recognized as in message is also part "on local host with Unicode ERROR partner '.*..**:" where *.*... is IP address..

That problem occurred after some patches were implemented.

@2.) I can't change it to ABAP proxy
