MA540 - Attempt to access item beyond bounds of memory Error

Hi all, I have a scenario where our Job MA540 fails and goes into "Needs Recovery" when we do the matching on an Invoice that has taxes in MA54 and try to run MA540 it goes to "Needs Recovery" with the following Generic Cobol message : \n Execution error : file 'D:\lawlsf\apps\lsfprod\obj\MA540.gnt' \n error code: 114, pc=0, call=1, seg=0 114 Attempt to access item beyond bounds of memory (Signal 11) I recompiled the program with trace on, and I see that it fails at the subroutine 900-CALC-VERTEX-TAX ( as we are using Vertex for taxation ) the generated mdfebug file shows the following : D:\Cobol\Base\Bin\WIN64\run.exe caused an exception at address : 0x00000001800404F5 Exception type - EXCEPTION_ACCESS_VIOLATION on Read.

Any Idea how to deal with this issue or someone had similar issue in the past ? OS : Windows 2008 R2 S3 9.0.1.11 Thank you Thank you
