I took a look with "free -m" and the situation looked entirely different. Also, I found the true cause of that one system crash and it had nothing to do with memory. My program was going through the scipts in /etc/init.d and doing a "status" on them to see what processes were up. It turns out that in openSUSE 11.4, that directory contains a script called boot which isn't a startup script at all, but the first script run at system startup, which does a lot of very basic things like mounting file systems. So, when my program gave the command:
service boot status
it was simply ignoring the command line argument "status" and executing, causing my program to stop and often causing a crash of my whole virtual environment. It had nothing to do with running out of resources.
Thanks again, Corona.

vxvoladmtask
vxvoladmtask(1M) vxvoladmtask(1M)
NAME
vxvoladmtask - administer ISP tasks
SYNOPSIS
vxvoladmtask abort task_tag
vxvoladmtask clear [task_tag]
vxvoladmtask list
vxvoladmtask [-t time] [-n] monitor task_tag
vxvoladmtask set task_tag=new_task_tag
DESCRIPTION
The vxvoladmtask utility can be used to perform basic administrative operations on tasks that have been created by the Intelligent Storage
Provisioning (ISP) feature of Veritas Volume Manager (VxVM). You can use the command to list ISP tasks, to monitor their states, and if
required, to cancel tasks.
KEYWORDS
abort Cancels the specified ISP task.
clear Removes all ISP task objects from the specified task. If no task is specified, this keyword clears all task objects for tasks
that have a status of CANCELLED, DONE or FAILED.
help Displays information on vxvoladmtask usage.
list Lists all ISP tasks.
monitor Monitors the specified ISP task.
set Renames the tag for an ISP task.
OPTIONS
-n Monitors ISP tasks that are newly registered while the program is running, as well as the specified ISP tasks. This option
applies only to the monitor keyword.
-t time Exits monitoring after time seconds. This option applies only to the monitor keyword.
EXAMPLES
List all ISP tasks:
vxvoladmtask list
Remove the ISP task object with the tag, Task1:
vxvoladmtask clear Task1
Cancel the allocator task object with the tag, Task2:
vxvoladmtask abort Task2
EXIT STATUS
The vxvoladmtask utility exits with a non-zero status if the attempted operation fails. A non-zero exit code is not a complete indicator
of the problems encountered, but rather denotes the first condition that prevented further execution of the utility.
