Message is failing when large volume of data for Proxy-to-File scenario in 7.31 single stack

Hi folks,

My scenario is Proxy to file(multiple files- total 6 files 4 for delta load or 2 for full load). PI version is single stack 7.31.

we have condition at interface determination which decide to create 4 files or 2 files. message is successful when size of message is less but when I am checking with message size approx 13MB message is giving the error as below

error is coming in :

SOAP: Call failed: com.sap.aii.adapter.xi.routing.RoutingException: Cant determine interface determinations because condition evaluation failedcom.sap.aii.adapter.xi.routing.condition.ConditionException: Could not resolve needed Extractors for ConditionFragment with Object-Id: 44ff5f2bcafa11e3cf6d5cac4cc62a86

Please help me to resolve this .
