I don't think that it's related to the engine. I've never seen it on any ovirt setup that I have. Anyway, you can try running: lsof -c ovirt | wc -l In order to see how many open files ovirt is using. Changing the limits of the OS shouldn't cause any bad behaviour. You can read a little bit about it - there is a soft limit and a hard limit. ----- Original Message -----

Thank you for your fast reply,
currently the maximum is set to 1024. I'll check back with my colleagues when they are in the office again. A quick check on some different systems shows this seems to be pretty standard behaviour, so why should it cause problems?
Can this be circumvented in the agent? I must look first into what side-effects this change may introduce.

run: ulimit -a
And see what's the current value for "open files".
Then increase it with: ulimit -n <new_number>
If it solved the problem, you need to edit /etc/sysctl.conf so it'll persist after reboot. add: fs.file-max = <new_number>

Hi,
I just stumbled upon the following in my guest-agent log on ubuntu 12.04.3 lts server:
MainThread::INFO::2014-01-06 14:29:29,106::ovirt-guest-agent::37::root::Starting oVirt guest agent MainThread::ERROR::2014-01-06 14:29:29,107::ovirt-guest-agent::117::root::Unhandled exception in oVirt guest agent! Traceback (most recent call last): File "/usr/share/ovirt-guest-agent/ovirt-guest-agent.py", line 111, in <module> agent.run(daemon, pidfile) File "/usr/share/ovirt-guest-agent/ovirt-guest-agent.py", line 42, in run self.agent = LinuxVdsAgent(config) File "/usr/share/ovirt-guest-agent/GuestAgentLinux2.py", line 324, in __init__ AgentLogicBase.__init__(self, config) File "/usr/share/ovirt-guest-agent/OVirtAgentLogic.py", line 90, in __init__ self.vio = VirtIoChannel(config.get("virtio", "device")) File "/usr/share/ovirt-guest-agent/VirtIoChannel.py", line 150, in __init__ self._stream = VirtIoStream(vport_name) File "/usr/share/ovirt-guest-agent/VirtIoChannel.py", line 131, in __init__ self._vport = os.open(vport_name, os.O_RDWR) OSError: [Errno 24] Too many open files: '/dev/virtio-ports/com.redhat.rhevm.vdsm'
Guest agent version is:
1.0.8.201309301944.gitb7f8f2-1p
Another question: How to disable the logging from the agent?
I just tried to set the following in /etc/ovirt-guest-agent.conf:
[handler_logfile] class=handlers.RotatingFileHandler #args=('/var/log/ovirt-guest-agent/ovirt-guest-agent.log', 'a', 100*1024, 5) args=('/dev/null', 'a', 100*1024, 5)
and then restarted the service -- Mit freundlichen Grüßen / Regards
