Bug Description
CID 201102-7188.
As part of certification testing, machines undergo a stress test to see how they perform under heavy load.
This particular system started being unstable with Ubuntu 12.04. On prior releases (I just retested with Oneiric and kernel 3.0.0) it's rock-solid and is able to complete the 2-hour stress test.
On 12.04, I've seen three possible failure scenarios (and so far, no success completing the test run):
1- The test runs for 2 hours but upon finishing it exits with signal 9.
2- The test runs for less than 2 hours, exiting because some of the workers got signal 9.
3- The system freezes before 2 hours have elapsed, requiring a reboot.
How to reproduce:
- Install Ubuntu 12.04
- apt-get install stress
- On a terminal, run:
stress --cpu 4 --vm 4 --timeout 7200
I'm not sure this bug belongs in the kernel, but I hope it's a good starting point.
