Java HotSpot VM (build 1.3.1-beta-b16) hangs up while running the test

    nsk/stress/network/network003

This was observed in server and client java_g VMs in -Xmixed mode and
server and client java VMs in -Xmixed, -Xint, -Xcomp modes under WinNT
(Win NT 4.0 Server P-II with two processors, 350MHz, 512Mb RAM).

This test passes fine on other platforms (Linux, Solaris Sparc,
Solaris Intel) on ladybird-b16 and works less then 5 minutes.

Also, the test passes on merlin-b50 on all four platforms (Linux,
Solaris Sparc, Solaris Intel, Windows) in -Xmixed, -Xint, -Xcomp
modes on both server and client VMs.

The test belongs to the testbase_nsk testbase located at:

    /net/sqesvr.eng/export/vsn/VM/testbase/ladybird/testbase_nsk
    
To reproduce the failure please use 'doit.sh' script found
in the directory:

    /net/sqesvr.eng/export/vsn/VM/GammaBase/Bugs/<this bug number>

Use:
    sh doit.sh $JAVA_HOME

This failure is probably explained in the bug

Behavior described in this bug is very similar to the VM hang-up
while executing the following test from testbase_nsk:

nsk/stress/network/network006

The HS 1.4.0-beta-b58 VM hang-up is rarely observing on
Solaris 8/x86 (Dual P-III 600MHz, RAM 512Mb).

I've noticed the following:
usually the test takes 3-4 minutes to execute and after that
it passes, but if after this 3-4 minutes the test is still running,
it will never end.

I agree that the bug 4311711 possibly describes an actual problem.
