I've got that problem periodically (XCP 0.5 we still using for older pool in product) in case of low resources for dom0. Solution: add more cpu to dom0, raise memory for dom0.

After relaxing resource problem I've never get that condition for prolonged time (>4 month) under pretty high loaded pool.

Hello, I have a problem with XCP 1.0. In recent weeks I saw very
resource openvswitch cpu and memory, no memory. At point (after a
while, less than a week) reaches the limit (512) and also begins to
swap out the point of leaving inoperative the real host and hence
their virtual machines. Everything returns to normal when I restart
the daemon (/ etc / init.d / openvswitch) but I can not be doing it
all the time. Someone can give me some tips to keep looking?

Leave some logs that may be useful:
#tail -f /var/log/openvswitch/ovs-vswitchd.log

If you need any more information do not hesitate to ask me because I
can not find the way to the solution and I'm several weeks into this.

PD: my english sucks
