got a huge problem with openvz and LVS.
take 2 nodes with Linux version 2.6.26-1-openvz-686 (Debian 2.6.26-11), one (vz1) has ldirectord on CT0 and one VE (ve1), next (vz2) has just one VE (ve2).
if ldirectord (from vz1) is directing traffic to vz2 : all work fine, but if traffic is redirected to local CTO (vz1) kernel thread ksoftirqd takes 100% of the cpu and nothing else happens !
With tcpdump we can see numerous paquets forwarded to ve1, something similar to a loop !!
setup :
