Filenet GetContent webservice returns the file incomplete - filenet-p8

Question

I am using Filenet 5.2.1 soap webservice GetContent :
http://myserver:9080/wsi/FNCEWS40MTOM.wsdl
and when trying to get content for a file that is larger than 1 MB, the returned response when read as base64 is only for part of the file not the whole file.
my request is as follows :

Answer 1

The problem was in filenet configuration :
Inline Content Retrieval Limit default is 1 MB so that filenet webservice itself was returning 1 MB only of the file.
Increasing the value fixed the issue, but unfortunately the maximum is 10 MB.
