Description of problem:
When running RedHat AS 3.0 update 4 with Fujitsu Eternus storage attached via iscsi the system runs out of memory and then hangs. I am running 34 dd jobs that write a 4G file to each of the 34 luns that are mounted as ext2 filesystems. If I run only 17 dd jobs then the system doesn't fail. Also If I run a smaller file size then the system doesn't fail.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Attach your RedHat 3.0 system to a Fujitsu Eternus storage array
2. Create and mount 34 filesystems
3. Run 34 dd jobs at the same time to write 4G to each fileystem
Actual Results: System runs out of memory
Expected Results: System should not run out of memory
System I am running on is a Dell PE4600 with 2CPUs and 2.5G of RAM.

Console messages when problem occurs
As previously noted to all partners, Issue Tracker (IT) must be used by all Red
Hat Partners to open new bugs or feature req's. This is imperative as IT is the
method used to manage and prioritize the issues.
Closing this BZ now until an IT is opened. If you wish to open the IT and then
just copy this info and reopen the BZ, that is fine, but the BZ cannot be
processed without an open IT.
If this is part of the Fujitsu Japan group, it will also need to go through
Fujitsu L3Support first, who will then work with the Red Hat L3support group and
