Hi Arne, We run into this problem with swift regularly. We use the conntrack tools previously mentioned to increase the limits via puppet: https://github.com/NeCTAR-RC/puppet-swift/commit/20f9eb753198bf1624e0691b4f0ebbc70c3dd3de The swift deployment guide also recommends increasing this value: http://docs.openstack.org/developer/swift/deployment_guide.html Regards, Marcus.
