Error opening RFC connection Inbound message expired.

[former_member6134]

Hi Guys,

       The problem is about RFC connection in a scenario from R/3 (RFC) - PI - SOAP. When the program is executed on the R/3 side, the error we are getting is "call to messaging system failed: com.sap.engine.interfaces.messaging.api.exception. MessagingException: XIAdapter Framework".

When we are checking in SXMB_MONI then we are getting the following error:     

com.sap.engine.interfaces.messaging.api.exception.MessageExpiredException: Message 5e0626c0-69fd-11e2-8456-00096baefe5c(INBOUND) expired

When we try to check the RFC connection on R/3 side using SM59 transaction -> connection test we are getting the error of connection failed "Error in opening an RFC connection".

The pattern of this problem is that it occurs only during sometime of the day and it works at other time of the day. From the error message it appears that due to connectivity issue between R/3 and PI server there is time out and we are getting a Message expired exception.

How can we tackle such problem? Is there any fine tunning to be done on the R/3 side to establish the connectivity at all the time of the day irrespective of the load and traffic on the server. Can somebody help to resolve this issue?

Thanking You

With Best Regards

Hey,

This is a well documented issue related to a timeout during connection. Try increasing the xiadapter.inbound.timeout.default
