-----------------------------------------
Summary: OOM Kills Guests
Key: CLOUDSTACK-8678
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8678
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Hypervisor Controller, KVM
Affects Versions: 4.4.2
Environment: Intel Xeon Quad Core CPU L5520 @ 2.27GHz
98 GB RAM
Ubuntu 14.04
Running Cloustack 4.4.2
Reporter: Josh Harshman
Priority: Critical
We have several KVM nodes running Cloudstack 4.4.2. Sometimes an instance with
X amount of RAM provisioned will be started on a host that has X+a small amount
of RAM free. The kernel OOM killer will eventually kill off the instance. Has
anyone else seen this behavior, is there a way to reserve RAM for use by the
host instead of by Cloudstack? Looking at the numbers in the database and the
logs, Cloudstack is trying to use 100% of the RAM on the host.
Any thoughts would be appreciated.
Thank you,
