File Size issue during processing from SAP to PI7.4

Hello All,

Interface scenario : Proxy to File

System : SAP PI 7.4  (java stack only)

we are facing File size issue when sending huge file around 140 MB from SAP to PI 7.4 . Message are failing SAP  SXMB_Moni with Bad request error.

Same interface was working fine in PI 7.1 and after migrating to SAP PI 7.4 we start getting this issue and not able to send any file to target system as file is not coming to PI and it's failing SAP itself.

Please suggest what configuration setting we need to do to resolve this issue in PI 7.4 .

Any quick help will be appreciable as this is also impacting  Production system's file .

Regards,

Rajeshwar Singh
