We've been doing some load testing with WAS on RHEL4 under VM, and the other 
day something weird came up.

The machine is defined with 1.3 gb. storage under zVM 5.2, and about 1.5 gb. 
swap space in two partitions:  One about 1 gb. (dasdf), and the other about .5 
gb. (dasdd)

We use a product called "Teamquest" to monitor the system during the test, and 
as we were running, it suddently reported "dasdf" was 100% full.  WAS started 
to choke, and analysis of a crashdump appeared to show threads hung consistent 
with malloc failures.

We've been going around trying to figure out: 1) why we suddenly should have 
run out of virtual memory (if we did, because we never even got close to that 
before), and 2) why it was reported in this way.  Does anyone know if there's 
anything in the swap space management mechanism that would cause Linux to fail 
malloc if a single swap partition fills up?  Is there some kind of process 
affinity for paging to swap spaces?
