Hi All Three days ago we started to see some problems on one of hour XEN hosts: The server is a Centos 5.3 with xen 3.4.1 from Gitco rep. sometimes some domains (win 2k3 server) crashes with this messages from xend log: device model failure: pid 17081: malfunctioning (closed sentinel), killed; see /var/log/xen/qemu-dm-xxx.log in the qemu log the last line is: raw_aio_remove: aio request not found! the domain config file is: name = "abc" kernel = "/usr/lib/xen/boot/hvmloader" builder = "hvm" device_model = "/usr/lib64/xen/bin/qemu-dm" disk = ["phy:/dev/disk/by-path/ip-10.20.30.1:3260-iscsi-vsp:1070-lun-1,hda,w","tap:aio:/opt/vservers/isos/rescue,hdc:cdrom,r"] memory = 2048 maxmem = 2048 vcpus = 4 cpu_weight = 1 acpi = 1 apic = 1 vif = [ "mac=00:16:3e:c1:a2:a3" ] boot = "c" vnc = 1 vncdisplay = 111 vncpasswd = "1234" keymap = "it" usbdevice = "tablet" on_poweroff = ''destroy'' on_reboot = ''restart'' on_crash = ''restart'' What can i check ?

Anyone knows something about that ? I see that in the bugzilla there''s some qemu-related bugs opened in the 2007 and never closed (!!!)
