#### Issue Description I’m trying to run the ImdbReviewClassificationRNN from the dl4j examples repo with a cpu configuration rather than gpu and am getting this error: ```auto # # SIGSEGV (0xb) at pc=0x00007fb000df0e79, pid=29020, tid=0x00007faff8926700 # # JRE version: Java(TM) SE Runtime Environment (8.0_261-b25) (build 1.8.0_261-b25) # Java VM: Java HotSpot(TM) 64-Bit Server VM (25.261-b25 mixed mode linux-amd64 compressed oops) # Problematic frame: # C [libnd4jcpu.so+0x5bc0e79] void functions::transform::TransformAny::exec >(void const*, long long const*, void*, long long const*, void*, unsigned long, unsigned long)+0x1789 ``` This has run successfully before an another host but fails on the current host I’m on and I’m not sure what’s causing it to fail. #### Version Information Please indicate relevant versions, including, if relevant: - Dl4J/ND4J version: 1.0.0-beta7 - Java version: java version “1.8.0\_261” Java™ SE Runtime Environment (build 1.8.0\_261-b25) Java HotSpot™ 64-Bit Server VM (build 25.261-b25, mixed mode) OS version: NAME=“Red Hat Enterprise Linux Server” VERSION=“7.8 (Maipo)” 3.10.0-1127.18.2.el7.x86\_64 #### Additional Information Core stack trace ```auto #1 0x00007fb0d637ea78 in abort () from /lib64/libc.so.6 #2 0x00007fb0d5c66b59 in os::abort(bool) () from /efs/dist/oracle/jdk/1.8.0_261-build001/.exec/x86-64.rhel.6/jre/lib/amd64/server/libjvm.so #3 0x00007fb0d5e2eb43 in VMError::report_and_die() () from /efs/dist/oracle/jdk/1.8.0_261-build001/.exec/x86-64.rhel.6/jre/lib/amd64/server/libjvm.so #4 0x00007fb0d5c70e05 in JVM_handle_linux_signal () from /efs/dist/oracle/jdk/1.8.0_261-build001/.exec/x86-64.rhel.6/jre/lib/amd64/server/libjvm.so #5 0x00007fb0d5c63ca8 in signalHandler(int, siginfo*, void*) () from /efs/dist/oracle/jdk/1.8.0_261-build001/.exec/x86-64.rhel.6/jre/lib/amd64/server/libjvm.so #6 #7 0x00007fb000df0e79 in void functions::transform::TransformAny::exec >(void const*, long long const*, void*, long long const*, void*, unsigned long, unsigned long) () from //data/test/.javacpp/cache/dl4j-examples-1.0.0-beta7-shaded.jar/org/nd4j/nativeblas/linux-x86_64-avx2/libnd4jcpu.so #8 0x00007faffbe5953d in std::_Function_handler::_M_invoke(std::_Any_data const&, unsigned long&&, std::_Any_data const&) () from //data/test/.javacpp/cache/dl4j-examples-1.0.0-beta7-shaded.jar/org/nd4j/nativeblas/linux-x86_64-avx2/libnd4jcpu.so #9 0x00007fb00164ca41 in samediff::Threads::parallel_do(std::function, unsigned long) () from //data/test/.javacpp/cache/dl4j-examples-1.0.0-beta7-shaded.jar/org/nd4j/nativeblas/linux-x86_64-avx2/libnd4jcpu.so #10 0x00007faffbe8b0ca in NativeOpExecutioner::execTransformAny(sd::LaunchContext*, int, void const*, long long const*, void const*, long long const*, void*, long long const*, void*, long long const*, void*, long long const*, long long const*, bool) () from //data/test/.javacpp/cache/dl4j-examples-1.0.0-beta7-shaded.jar/org/nd4j/nativeblas/linux-x86_64-avx2/libnd4jcpu.so #11 0x00007faffbe90d15 in execTransformAny () from //data/test/.javacpp/cache/dl4j-examples-1.0.0-beta7-shaded.jar/org/nd4j/nativeblas/linux-x86_64-avx2/libnd4jcpu.so #12 0x00007faffaf4fc2e in Java_org_nd4j_nativeblas_Nd4jCpu_execTransformAny__Lorg_bytedeco_javacpp_PointerPointer_2ILorg_nd4j_nativeblas_OpaqueDataBuffer_2Lorg_bytedeco_javacpp_LongPointer_2Lorg_bytedeco_javacpp_LongPointer_2Lorg_nd4j_nativeblas_OpaqueDataBuffer_2Lorg_bytedeco_javacpp_LongPointer_2Lorg_bytedeco_javacpp_LongPointer_2Lorg_bytedeco_javacpp_Pointer_2 () from //data/test/.javacpp/cache/dl4j-examples-1.0.0-beta7-shaded.jar/org/nd4j/nativeblas/linux-x86_64-avx2/libjnind4jcpu.so #13 0x00007fb0c1190bf9 in ??

Did you fix it? I encountered the similar issue. # Problematic frame: # C [libnd4jcpu.so+0x58b5df0] sd::TadDescriptor::TadDescriptor(long long const\*, int const\*, int, bool)+0x460 ---

While it is the same kind of issue, it isn’t necessarily the same issue. That is a lot like saying that an exception has been thrown. Please create a new thread and share more information with us about what you were doing. ---

@arnaud22 yes please do as @treo mentioned. Causes for this can vary quite a bit. Sometimes from multi threading all the way to a c++ issue. It’s hard to tell without reproducing it. Preferably you give us code we can run or at least the hs\_err\_pid\_\*.log somewhere in the directory where the crash happened.
