Error description

  • Error Message: A dump event "traceassert" is received in a
    system when the calling process's virtual address space is
    locked into RAM.
    .
    Stack Trace: The native stack trace looks like this:
            j9dump_create ()
            doSystemDump ()
            j9sig_protect ()
            runDumpFunction ()
            runDumpAgent ()
            triggerDumpAgents ()
            doTracePoint ()
            j9Trace ()
            j9vmem_decommit_memory ()
            MM_VirtualMemory::decommitMemory ()
            MM_PhysicalSubArenaVirtualMemoryFlat::contract ()

            MM_ConcurrentGC::internalGarbageCollect ()
            MM_Collector::garbageCollect ()
    .
    The following traces can be found in the Snap trace:
            j9prt.1296           Exception  * j9vmem_decommit_memory
    failed with platform specific error code=22 at
    address=0xdc000000 byteAmount=917504
            j9prt.504            Assert     * ** ASSERTION FAILED **
    at linux/j9vmem.c:321: ((0 == result))
    

Local fix

  • This issue can be worked around if the value of -Xms is set to
    the same as that of -Xmx.
    

Problem summary

  • The problem is caused when a process's virtual address space is
    de-committed while it is locked.
    

Problem conclusion

  • The JVM has been updated to prevent the assertion failure when
    the process's virtual address space is locked.
    .
