IO Stress utility fail to run(Kernel: VM: Killing process)
Last modified: 2005-10-31 17:00:50 EST
IO stress utility failed with the messages attached below.
This problem occurs on various types of drives on various controllers. I
encountered this problem during heavy IO activities on drives on cpqfc, IDE
(ATA-100), cpqarray, and cciss drivers.
System: DL320(single PIII 1Ghz, 128MB RAM, 256MB swap)
ML530(Dual PIII 1Ghz, 128MB RAM, 256MB swap)
DL380 G2(Single 1.33Ghz, 256RAM, 512MB swap)
filesystems: ext2, ext3
OS: fairfax Beta2
Controller: SA5300, Embedded IDE(ATA100), SA532, SA5i, SA4200
Steps to reproduce:
1. Install OS
2. Create partitions(I tried 2G to 14G) with ext2 or ext3
3. mount partitions
4. Start IO stress utility(anything that creates heavy IO activities)

we're aware of the "early kills" of the VM and doing our best to fix them as
soon as possible. Thanks for the report.
This defect is considered SHOULD-FIX for Fairfax.
Roswell beta has this fixed. However it's slow in other respects.
Closing this bug but be assured: VM is a very high attentionpoint for us.
