Crash during start up in _int_malloc() (libc) due to SIGSEGV

XMLWordPrintable

    • x86
    • linux

      Have seen occasional crashes during start up when running on Exalogic x2-2. The crash is reproducible but happens very seldom, something like 1 in 10000. It is reproducible on both jdk 7 and 8.

      The way I reproduce it is by running HelloCrash (like HelloWorld) over and over:
      while true; do java -Xms4096m -Xmx4096m HelloCrash; sleep 0.2; done

      The crash always seems to happen in _int_malloc and then the JVM often crashes again during crash handling. The stack trace before the call to malloc differs and I have not seen any real pattern.

      The Exalogic is running:
      Linux sthex01-srv06 2.6.32-400.1.1.el5uek #1 SMP Mon Jun 25 20:25:08 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux

      jdk7:
      java version "1.7.0_12-ea"
      Java(TM) SE Runtime Environment (build 1.7.0_12-ea-b03)
      Java HotSpot(TM) 64-Bit Server VM (build 24.0-b25, mixed mode)

      jdk8:
      java version "1.8.0-ea"
      Java(TM) SE Runtime Environment (build 1.8.0-ea-b66)
      Java HotSpot(TM) 64-Bit Server VM (build 25.0-b10, mixed mode)

      Will attach some hs_err-files and cores. If needed I can provide more cores later, have around 50.
