I've just tried the test b4432433 against Hopper-b18 for Linux. 
At 1-CPU machine, both client and server VMs passed the test; 
and at 2-CPU machine, both client and server VMs have crashed. 

The machines I've used are:
- 1xPIII 866MHz, 512Mb RAM, Linux RedHat 7.2
- 2xPII  600MHz, 512Mb RAM, Linux RedHat 7.2

For me, it looks like the test reveals the known HotSpot problem 
described by the bug 4432433. The problem is that HS crashes on 
some real end-user applications when lots of RAM is required. 

However, I cannot see: why is this test assumed erroneous?

I've updated the cfg file of the test to use LIMIT_HEAP_SIZE variable from
ini-files in -Xmx option. The default value of LIMIT_HEAP_SIZE is 1024 (1GB).

This bug relates to test which is included into nsk.killer.tests list,
so I'm closing this bug as a duplicate of 

  4732445 TEST: some tests may prevent Tonga from completing jobs

See evaluation of 4732445.

Fixed in testbase_nsk.v142r17
