Hi,

  It looks like you are having two separate problems - disk space for the sort file and accessing a large amount of physical memory.

  For the disk space, you were exhausting the space on the drive that SAS was using for temporary space.  I've changed the SAS configuration to use a different location for temporary space - this should have more than 4 GB available.

  The memory limit is a specific limit set on the head node of the cluster to make sure resources are available for all users and management process.  To access more memory, you should use our larger memory node, which has 16 GB of physical memory.  To access this node, login to the cluster and then do "ssh c-0-0" and then run sas using the same process you used on the head node. 

  If you're still having problems, let me know - it is possible that the 4 GB memory limit may be due to a limitation in SAS, but I would have to confirm this with SAS.

Subject: SAS "probable disk full condition"

Hi,

I am currently using SAS to run programs for my graduate thesis. I have to sort a 3 GB file, and SAS gives the following error:
"ERROR: Utility file write failed.  Probable disk full condition."

I tried referring to various sources, but couldn't find a correct solution. 
- please let me know if there is any way to increase the size of this utility file. A sample program would be very helpful.
- Also, even if I allocate "sas -memsize 10240m", it always allocates a max memory of 4 GB. Is there any way to increase this memory allocation? 

This is my program for reference:

data lookup;
infile '/ibrixfs1/home/ramakrs/thesis/Kendals/GOSemanticSimilarityBL_val.txt' dlm=' ' missover pad;
input goTerms $21. simVal $10.;
run;
proc sort data=lookup; by goTerms; run;

The lookup file is 3.2 GB in size and fails during sort. 


Thank you very much,
Sriram
