Hello everybody,at the moment we're have a strange problem during high load on our DOMUs Network services became unavailable for a short period connection time takes several seconds. Will the service (tomcat) is still available from inside of the domU connections from DOM0 and even from other servers hangs. If tried to desiable checksuming (ethtool -K eth0 tx off) on DOMUs interface netstat output DOMU is as follows: netstat -an|awk '/tcp/ {print $6}'|sort|uniq -c ============================= 231 ESTABLISHED 259 FIN_WAIT2 1 LAST_ACK 6 LISTEN 340 TIME_WAIT brctl show on DOM0: ============= bridge name bridge id STP enabled interfaces eth0 8000.001ec9edee5e no peth0 vif135.0 vif144.0 xenbr1 8000.001ec9edee60 no eth1 xenbr2 8000.0015178538c2 no eth2 vif134.0 vif137.0 xenbr3 8000.0015178538c3 no eth3 vif143.0 vif148.0 One of DOMUs configuration: ===================== kernel = '/boot/vmlinuz-2.6.26-2-xen-amd64' ramdisk = '/boot/initrd.img-2.6.26-2-xen-amd64' extra='console=hvc0' memory = '2400' vcpus = '8' # # Disk device(s). # root = '/dev/sda1 ro'disk = [ 'phy:system/tomcat03-disk,sda1,w', 'phy:system/tomcat03-swap,sda2,w' ] # # Hostname # name = 'tomcat03' # # Networking # vif = [ 'ip=192.168.0.98,mac=00:16:3E:41:2C:18,bridge=xenbr3' ] # # Behaviour # on_poweroff = 'destroy' on_reboot = 'restart' on_crash = 'restart' How can I repeat?
