https://github.com/FelixYBW/gluten/commit/fbfe0f30b99d8fb759c9eb447968af4ab7a3f4dd Here is a simple way to detect this. It output the memory allocation bigger than 1M but not from memory pool. disable jemalloc, set executor.core to 1, then you can get output like ``` allocated 67108864 libvelox.so(+0x15b4ff5) [0x7f3301cf2ff5] libvelox.so(+0x15b51eb) [0x7f3301cf31eb] libgluten.so(_Znwm+0x19) [0x7f3307be9ea9] libvelox.so(_ZNSt6vectorISt10shared_ptrIN8facebook5velox4exec15WindowPartitionEESaIS5_EE17_M_realloc_insertIJS5_EEEvN9__gnu_cxx17__normal_iteratorIPS5_S7_EEDpOT_+0x80) [0x7f3305130180] libvelox.so(_ZN8facebook5velox4exec24RowsStreamingWindowBuild18addPartitionInputsEb+0x1cf) [0x7f330512f18f] libvelox.so(_ZN8facebook5velox4exec24RowsStreamingWindowBuild8addInputESt10shared_ptrINS0_9RowVectorEE+0x419) [0x7f330512f799] libvelox.so(_ZN8facebook5velox4exec6Window8addInputESt10shared_ptrINS0_9RowVectorEE+0x53) [0x7f3304bda5b3] libvelox.so(_ZN8facebook5velox4exec6Driver11runInternalERSt10shared_ptrIS2_ERS3_INS1_13BlockingStateEERS3_INS0_9RowVectorEE+0xfb9) [0x7f3304b5e0f9] libvelox.so(_ZN8facebook5velox4exec6Driver4nextEPN5folly10SemiFutureINS3_4UnitEEE+0xbb) [0x7f3304b5f63b] libvelox.so(_ZN8facebook5velox4exec4Task4nextEPN5folly10SemiFutureINS3_4UnitEEE+0x384) [0x7f3303124514] libvelox.so(_ZN6gluten24WholeStageResultIterator4nextEv+0x78) [0x7f3301ce78f8] libgluten.so(Java_org_apache_gluten_vectorized_ColumnarBatchOutIterator_nativeHasNext+0x139) [0x7f33071c99c9] ``` In this example, the root cause is ``` windowPartitions_.push_back(std::make_shared<WindowPartition>( pool_, data_.get(), inversedInputChannels_, sortKeyInfo_)); ``` Solution is to set `memory::StlAllocator<char*>` to std::vector. -- This is an automated message from the Apache Git Service.
