Description Rick Hester 2007-04-18 11:16:17 EDT
Description of problem:
The memory cert test on a system with 192GB of memory failed apparently
due to the oom killer being invoked sometime during the test.   The
system had been installed with the default amount swap space which was
less than the amount of memory in the system.

I increased the swap space to greater than the amount of memory (in this
case it was about 1.5 times as much).   This resolved the oom killer 
problems and the test passed.

I would suggest that the hts documentation include a note about having
swap space greater than the amount of memory available.  (Or better yet
supply some formula for determining the minimum amount of swap required,
since it may not always require that much swap space.   For some systems
it will be a challenge to get that much swap.  The largest memory system
we have currently is 2TB and they are not getting smaller.)

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Run the memory cert on a system with more memory than the default swap
Actual results:
oom killer causes test to fail

Expected results:
test to pass
