Hi,
I'm trying to track down why my Foreman Centos7 VM continuously crashes wit=
h out of Memory errors on my ovirt-3.6 hosts and what seems to happen is th=
e following:
1. The Foreman VM only uses 1GB at the beginning and MOM over time reduces =
the memory size from 8GB Ram to the defined minimum of 2GB
mom.log:
2016-03-18 12:25:42,669 - mom.Controllers.Balloon - INFO - Ballooning guest=
:qvie-foreman from 2210584 to 2100054
2. When the VM needs RAM very quickly like if you do an 'cp /dev/zero /run/=
zero' the ovirt guest agent crashes with an out of memory error.
ovirt-guest-agent.log:
Traceback (most recent call last):
File "/usr/share/ovirt-guest-agent/OVirtAgentLogic.py", line 239, in doWo=
rk
self.sendUserInfo()
File "/usr/share/ovirt-guest-agent/OVirtAgentLogic.py", line 355, in send=

cur_user =3D self.dr.getActiveUser()
File "/usr/share/ovirt-guest-agent/GuestAgentLinux2.py", line 325, in get=
ActiveUser
users =3D os.popen('/usr/bin/users').read().split()
OSError: [Errno 12] Cannot allocate memory
3. Resulting in an MOM warning that it can't get any memory stats from the =
VM. Leaving the memory size at its minimum size:.
mom.log:
mom.Collectors.GuestMemory - WARNING - getVmMemoryStats() error: The ovirt-=
guest-agent is not active
Any chances to prevent that from happening? Or is this a bug in MOM / ovirt=
-guest-agent that should be fixed?
Greetings
Andreas
