Public bug reported: I am repeatedly seeing a SEGV from OpenJDK Runtime Environment (25.0.2+10) (build 25.0.2+10-Ubuntu-122.04) while running Tomcat, sometimes several a day. This is a new thing after upgrading to this version of the OpenJDK (from version 21.x)
I've been running with "LD_PRELOAD=/usr/lib/x86_64-linux- gnu/libjemalloc.so.2", but after switching to "libtcmalloc.so.2" it is still crashing with an identical trace. It does seem to work with the GlibC allocator but that will eventually run out of memory, and other JDKs (eg GraalVM) seem to be be fine with any allocation library. Every crash leaves me with a trace that begins with the following frames Current thread (0x00007f1b04f41400): JavaThread "http-nio-8080-exec-4" daemon [_thread_in_native, id=456365, stack(0x00007f1ac2d00000,0x00007f1ac2e00000) (1024K)] Stack: [0x00007f1ac2d00000,0x00007f1ac2e00000], sp=0x00007f1ac2dfa3b0, free space=1000k Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code) C [libjemalloc.so.2+0x11942] Java frames: (J=compiled Java code, j=interpreted, Vv=VM code) v ~RuntimeStub::nep_invoker_blob 0x00007f1b103c59e8 j java.lang.invoke.LambdaForm$MH+0x000000001a7c4400.invoke(Ljava/lang/Object;JFJJJIIIIIFFIIJJ)V+38 [email protected] j java.lang.invoke.LambdaForm$MH+0x000000001a7dfc00.invokeExact_MT(Ljava/lang/Object;JFJJJIIIIIFFIIJJLjava/lang/Object;)V+49 [email protected] j jdk.internal.foreign.abi.DowncallStub+0x000000001a7c4800.invoke(Ljava/lang/foreign/SegmentAllocator;Ljava/lang/foreign/MemorySegment;FLjava/lang/foreign/MemorySegment;Ljava/lang/foreign/MemorySegment;Ljava/lang/foreign/MemorySegment;IIIIIFFIILjava/lang/foreign/MemorySegment;Ljava/lang/foreign/MemorySegment;)V+317 [email protected] j java.lang.invoke.LambdaForm$DMH+0x000000001a7c5000.invokeStaticInit(Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;FLjava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;IIIIIFFIILjava/lang/Object;Ljava/lang/Object;)V+42 [email protected] j java.lang.invoke.LambdaForm$MH+0x000000001a7c6800.invoke(Ljava/lang/Object;FLjava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;IIIIIFFIILjava/lang/Object;Ljava/lang/Object;)V+75 [email protected] j java.lang.invoke.LambdaForm$MH+0x000000001a7df400.invokeExact_MT(Ljava/lang/Object;FLjava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;IIIIIFFIILjava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)V+46 [email protected] j sun.font.HBShaper.lambda$shape$0(Ljava/awt/geom/Point2D$Float;[F[CFLjava/lang/foreign/MemorySegment;IIIIII)V+79 [email protected] j sun.font.HBShaper$$Lambda+0x000000001a789d30.run()V+44 [email protected] j jdk.internal.vm.ScopedValueContainer.runWithoutScope(Ljava/lang/Runnable;)V+21 [email protected] j jdk.internal.vm.ScopedValueContainer.run(Ljava/lang/Runnable;)V+7 [email protected] j java.lang.ScopedValue$Carrier.runWith(Ljava/lang/ScopedValue$Snapshot;Ljava/lang/Runnable;)V+9 [email protected] j java.lang.ScopedValue$Carrier.run(Ljava/lang/Runnable;)V+29 [email protected] j sun.font.HBShaper.shape(Lsun/font/Font2D;Lsun/font/FontStrike;F[FLjava/lang/foreign/MemorySegment;[CLsun/font/GlyphLayout$GVData;IIIILjava/awt/geom/Point2D$Float;II)V+48 [email protected] j sun.font.SunLayoutEngine.layout(Lsun/font/FontStrikeDesc;[FFIILsun/font/TextRecord;ILjava/awt/geom/Point2D$Float;Lsun/font/GlyphLayout$GVData;)V+75 [email protected] etc While I can reliably reproduce this on our live site I'm unable to with an isolated version of Tomcat. But I'm attaching 43 hs_err files and my best effort to reproduce it, which will at least duplicate the codepath I'm seeing above. I appreciate this is probably an OpenJDK issue not an Ubuntu issue but I am not an OpenJDK dev so I'm unable to file a bug with them. I presume Ubuntu can push this upstream. ** Affects: openjdk-25 (Ubuntu) Importance: Undecided Status: New ** Tags: segv ** Attachment added: "error logs and a failed attempt at a generating a reproducible testcase" https://bugs.launchpad.net/bugs/2155650/+attachment/5975818/+files/tomcatcrash.zip -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2155650 Title: OpenJDK 25.0.2 SEGV To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openjdk-25/+bug/2155650/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
