ERROR <FILEFULL>%SaveData

Hello,

I'm using a ComplexBatchFileService to retrieve and process a 425 Mo File ( lines ) 

At some point the Business Service is in failure , and displays this error : 

ERREUR #5002: Erreur Cache: <FILEFULL>%SaveData+18 ^CFAO.EOS.MasterFilePR.PMP.RM.ART1.Record.1 ^CFAO.EOS.MasterFileE50F.RecordD(535405931),e:\eos\
+
ERREUR #5002: Erreur Cache: <ROLLFAIL>%TRollBack+10 ^%occTransaction

Do you have any idea about the cause of this error ? ( i have checked the iris databases disk space and it's not full )

Thank you in advance.
