Several people have run into problems when attaching large disk arrays to a mainframe because of running /sbin/hotplug as a bash script takes far longer than the interval between hotplug events. Attaching more than 300 devices at once will cause an out-of-memory condition and the kernel starts killing random processes. Running only udev instead of hotplug from the kernel is fast enough.

Hello, The current dependancy on hotplug|udev (>= 0.59) seems bad. As far as I remember, last week, when I tried to install Ralph packages, I got an error from hotplug/udev and I had to use udev from backports.org Anyone know which version of udev/hotplug we will have to depends on ? Maybe we could simply rely on a recent udev dependancy, because afaik udev now provides hotplug. -- Julien

What subsystem replaces /sbin/hotplug in CentOS 5? The older hotplug package is missing from CentOS 5 and /proc/sys/kernel/hotplug yields an empty string. Since hotpluging for standard devices still seems to work, I presume that something replaces the hotplug helper found on CentOS 4. Can someone point me in the right place? All of my Googleing points me back to the (obsolete?) /sbin/hotplug

Hello all, Been using Xen a while, previously with Netbsd and few weeks ago changed dom0 to Gentoo linux. Change wen''t very nice, but now I''m facing strange out of resources problem in Windows XP HVM guests. At first there was no issues but when we added second windows guest users started to complain that they cannot access network drivers and cannot unzip large zips ( the

We''ve been noticing a lot of these errors when booting VMs since we moved to 3.0.3 - I''ve traced this to the hotplug scripts in Dom0 taking >10s to run to completion and specifically the vif-bridge script taking >=9s to plug the vif into the s/w bridge on occasion - was wondering if anyone has any insight into why it might take this long. I added some instrumentation to

Hello, My name is Fermín Galán. I have started recently to use Xen (so please forgive me in advance if I''m too "newbie" :) and I''m facing my first problems...
