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.

    Well the problem appears to have been message overload.

    I reduced number of outbound queues and haven't seen the error since. We're putting SP16 on production this weekend so I'll keep my fingers crossed for next week.

    Thanks for the help.
