The current pool size limit (max connections) is 1 connections."

HI,

Make number of connections 20 in RFC adapter. you have option in RFC adapter for this make it 20.

See the below links

http://help.sap.com/saphelp_nw04/helpdata/en/f6/daea401675752ae10000000a155106/frameset.htm

See the SAP Note 831162 for increasing the no of connection.

Hey Swarup,

Why I shall make it "20"?

Is there any specific rason for "20"?

HI Indu,

You connection pool size is getting short, so normally increasing connection pools will resolve the problem.

If increase it more than the limit then its problem to fail the load balancing, so I had said it to 20...this normally worked as per my past experience.

Thanks

Delivery of the message to the application using connection RFC_http://sap.com/xi/XI/System failed, due to: com.sap.aii.af.ra.ms.api.RecoverableException: java.lang.NullPointerException.

u mite b getting this exceptiopn b'coz some context variable that is being retrieved has null as it's value and u havn't handled it.

try debugging your application and check if any of the context variables are havin null value.
