Bug Description
Upstream bug (for Ubuntu) - https:/
Description:
When using sar for system diagnostics (part of sysstat package), hitting Crtl+C to stop may cause system to be killed (rebooted).
Steps to reproduce:
1. install sysstat
2. run `sar -n DEV 1 | grep eth0`
3. hit Ctrl+C
4. sometimes (quite often) this causes system reboot (init gets SIGINT). If unsuccessful, try again a few times.
Expected results:
sar stops
Actual result:
sar stops, system goes into reboot
This has been reproduced in Ubuntu 14.04 on MOS 6.1 and on Fuel server on MOS 8.0.
Relevant upstream fix introduced in sysstat on Nov. 2014:

The sysstat package is a part of Ubuntu, we don't manage it. Moreover, it is not used in the normal workflow of an OpenStack cloud. So basing on the above, I'm setting the Importance to medium and closing this as Invalid. Please wait until the package is fixed upstream or avoid using it.
