Issues with volume of data sent using web service

Hi All,

I am using a web service to post data to XI using a soap adapter and sending the data from XI to SAP using a proxy. The data received from the web service is in base64 binary format. Whenever the file base64 binary is greater than 6MB, there is a message split. When I view the messages in SXMB_MONI transaction in XI, there are multiple messages for a single request sent from the third party tool.

Can anyone please provide some inputs on why there is a split in the messages when the file size is more than some 6MB?

What is the ideal message size that can be transferred through XI using webservices?

The webservice that I am referring is a synchronous one, where the response message is sent by the proxy once the data is updated into SAP. The message is logged in SXMB_MONI with status LOGVERSIONS, so does this status LOGVERSIONS mean there is a timeout in XI?

Thanks,

Manohar.
