I am importing a mildly large ~3gb xml file into SAS 9.4 on Windows.  When I do, I run into "The SAS System stopped processing this step because of insufficient memory."  However, when I (1) run this on a large-memory server and (2) increase the memsize and memmaxsz options to 500 gb each (verifying using proc options), it still gives the error.  I don't believe memory is actually the problem, because when I run "options fullstimer" I receive the results: NOTE: DATA statement used (Total process time):       real time           3:12.07       user cpu time       2:38.18       system cpu time     31.65 seconds       memory              1758.46k       OS Memory           15864.00k       Timestamp           09/08/2018 08:37:18 AM       Step Count                        5  Switch Count  3 Which suggests that the process isn't actually using much memory at all!  Any suggestions would be appreciated.   The full code I use is:    proc options; run; options fullstimer; libname in xml 'Y:\Flexibility\Devices.xml'; data Device; set in.Device (keep = device1 devicedescription devicecategory deviceregion devicepurpose price); run; proc export data = Device outfile='Y:\Device\Devices.txt' dbms=tab replace; run;   ...
