Hello,   I have a file of 9GB size. I tried to sort it on SAS U Edition. But it said "No disk space is available for the write operation." On the other hand, when I tried a smaller file, it run perfectly.   My computer is Mac OS 10.13.6 (17G3025), I have 150GB available space on my disk. I also set enough space on VM.   I don't know how to solve this problem and I also don't know is it true that the SAS U Edition only allow 5GB space for user.   Part of the code:   /* hg is my database name */   83 proc sort data=hg.hg01merged out=hg.newmh reverse; 84 by party_id company country shipment tel; 85 run;   ERROR: No disk space is available for the write operation. Filename = /tmp/SAS_util000100000978_localhost.localdomain/ut0978000005.utl. ERROR: Failure while attempting to write page 693 of sorted run 8.
