how to deal with Hash error "Hash object added 0 items when memory failure occurred." ?

Hi all,

I am running a do loop and got into this hash error, wonder how can I deal with this error. please note I'm runing with SAS EG on linux server. (SAS EG is on my laptop)

Detailed error info:

ERROR: Hash object added 0 items when memory failure occurred.

FATAL: Insufficient memory to execute DATA step program. Aborted during the EXECUTION phase.

ERROR: The SAS System stopped processing this step because of insufficient memory.

Possible solution I can think of:

1) Split big data set to small ones. I have total records about 3500000, it seems I need to split to at least 15 data sets. (I tested the small data set ran through the sas code successfully)

2) Increase the memory size?

I ran the code Proc Options group=memory; run; and the results are as follows:

Group=MEMORY

SORTSIZE=1073741824

Specifies the amount of memory that is available to the SORT procedure.

SUMSIZE=0 Specifies a limit on the amount of memory that is available for data summarization procedures when class

variables are active.

MAXMEMQUERY=268435456

For certain procedures, specifies the maximum amount of memory that can be allocated per request.

LOADMEMSIZE=0 Specifies a suggested amount of memory that is needed for executable programs loaded by SAS.

MEMSIZE=2147483648

Specifies the limit on the amount of virtual memory that can be used during a SAS session.

REALMEMSIZE=0 Specifies the amount of real memory SAS can expect to allocate.

Please advise what I should do, any suggestion is welcome. Thank you!

What are you trying to do with the hash? At 3.5 million records a plain sort/lookup may be better than a divide and conquer approach.

Thank you. I am use it for some do loop calculations. See details:
