Qi Ji commented on HARMONY-4890:
--------------------------------

Hi Vladimir,
    I followed your new description and run that command line for 5 times, but never got your
previous stack trace, the output is all the same as what I reported last week.
    BTW, we are employing a Fedora6 Linux 64bit system. 
    It seems that we should have enough patience to reproduce that "bug".

> I'm enabling EUT3.3 on Linux x86_64 (SLES10).
> A bit set of suites crashed with the following dump:
>      [java] SIGSEGV in VM code.
>      [java] Stack trace:
>      [java]   0: gc_gen_adapt(GC_Gen*, long long) (??:-1)
>      [java]   1: ?? (??:-1)
>      [java]   2: ?? (??:-1)
>      [java]   3: apr_atomic_casptr (atomic/unix/apr_atomic.c:376)
>      <skipped...>
> which allows to guess it is GC GEN issue to be fixed.
> The issue is reproduced on the machine with the 1024 limitation of open files. I.e. to
reproduce the crash you need to do this limitation with the command:
>     ulimit -n 1024
> Could someone take a look, please?
> Thanks
