V6-MIXED-D788 BY Statement or Multiple PROC MIXED Calls Can Cause Memory Problems

PROC MIXED may cause memory problems in the presence of a BY statement or if there are multiple invocations of PROC MIXED in the same SAS session. The procedure may not release all of the memory it requires for each model. If enough models are run in a single SAS session, then the procedure may incorrectly reserve too much memory for these models and not release enough memory for the next model to run.

The only circumvention for this problem is to run only one model or by-group in a SAS session, reinvoking SAS for each model that needs to be run.
