RTS 198

I'm using "Micro Focus COBOL Server 2.3.1142" on Windows Server 2012.
The same program compiled with Enterprise Developer 2.3.1 (Eclipse version) with same input data on my server work fine, instead on the server of customer give error rts 198.
the command line is:
C:\"Program Files (x86)"\"Micro Focus"\"COBOL Server"\BIN\RUN.EXE LBTESO37.DLL   1>E:\ALA90T\FILES\SYSOUT_LBTESO37.TXT
errorlevel = 198

The customer told me that mfdebug.log was not created .

I have attached mfsupportinfo and environment vars when error happens.
All other program (also DLL) work fine....
What can cause this error ?
