Sort problem

[Cesar Augusto]

Hi all

Well, I did a parallel job, and i used a 'Join' stage.
So, when the job ran with the real data (40,000,000 rows), the job aborted in the 'Join' stage, and show the error messages below:

"APT_ParallelSortMergeOperator,0: Failure during execution of operator logic."
"APT_CombinedOperatorController,0: Fatal Error: Throwing exception: APT_BadAlloc: Heap allocation failed."
"Join_CCR_Keys,0: Failure during execution of operator logic."
"Join_CCR_Keys,0: Fatal Error: waitForWriteSignal(): Premature EOF on node apdtcp001 No such file or directory"
"node_node2: Player 11 terminated unexpectedly."
"node_node1: Player 9 terminated unexpectedly."
"subArgs={asc}}},0: Failure during execution of operator logic."
"subArgs={asc}}},0: Fatal Error: Unable to allocate communication resources"
"TRF_JOIN,2: Failure during execution of operator logic."
"TRF_JOIN,2: Fatal Error: Unable to allocate communication resources"
...

Another programer said to use a "Sort" stage before the "Join"... this will works?

thanks for the atention

You are running out of both memory and communication resources. This suggests that your server is overloaded.
