Problem Note 62716: Aggregate Action might cause the SAS® LASR™ Analytic Server to become unresponsive
 |  |  |  |  |
The Aggregate Action in SAS LASR Analytic Server might attempt to access memory that has already been freed. This can cause the LASR Analytic Server to become unresponsive. A traceback message is written to the log of the affected worker node. The message includes a reference to the ComputeAggregate function, similar to the following:
#9 0x00007f03ceb8e298 in ComputeAggregate () from /sas/hadoop/TKGrid_3.4/TKGrid/lib/lasr.so
The only workaround for this problem is to restart the LASR Analytic Server.
