many instances of "/sbin/ifup ethx" coming from udev/hotplug
Hi all,
We're running a 2.6.14 kernel and have a situation where multiple (20 or so) ethx devices are being created in about 3 seconds. This appears to cause latency issues for other tasks on the system due to all the "/sbin/ifup ethx" processes that get created.
We're seeing these processes being created by udevd directly, by /sbin/hotplug, and by /etc/sysconfig/network-scripts/net.hotplug (which is in turn created by udevd).
Can someone shed some light as to why ifup gets called from three different places for the same event, and whether it's expected to cause latency issues? Also, is there anything we can do to streamline this?
Thanks,
Chris

What distro is that? It sounds like a pretty broken setup. :)

I don't think I should say, they might not appreciate it. ;)
So this is unusual? What's the expected path for ifup to be called in a current distro?

Usually it's called from a udev RUN rule only, and only once. /sbin/hotplug does not even exist on most distros today.
Maybe you have the "hotplug" package installed and you shouldn't?
