error code: 400, error text: ICM_HTTP_CONNECTION_FAILED

Every now and then we are getting the following error on a synchronous call from XI 3.0.

Error when receiving by HTTP (error code: 400, error text: ICM_HTTP_CONNECTION_FAILED)

Usually it is from XI to R/3 (that's where most of our synch calls take place) but occasionally it happen on a synchronous call to a JDBC comm channel.

It is not just one interface that causes this issue and the same interface will be OK if we re-run it with same data.

I suspect some system parameter is off, or it's just a bug in XI. Any one else run into this ? if so, have you found a fix ? SAP hasn't been much help for us thus far.

Thanks in advance for any help.

Hi Tim,

This happens generally because of message overflow.
