Created attachment 795598 [details] kernel-114.pcapng.bz2 It really helps to switch back to older kernel and I checked the logs and as IIRC problems started 5th of September, it correlates. Setting regression. I will check whether our other deployment suffers from this and whether I cannot get some more info. I can see those in messages: Aug 22 09:29:55 controller kernel: Linux version 2.6.32-358.114.1.openstack.el6.x86_64 (mockbuild.eng.bos.redhat.com) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC) ) #1 SMP Wed Jul 3 02:11:25 EDT 2013 Sep 4 17:09:27 controller kernel: Linux version 2.6.32-358.118.1.openstack.el6.x86_64 (mockbuild.bos.redhat.com) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC) ) #1 SMP Wed Aug 14 13:18:08 EDT 2013 Sep 5 10:06:45 controller kernel: Linux version 2.6.32-358.118.1.openstack.el6.x86_64 (mockbuild.bos.redhat.com) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC) ) #1 SMP Wed Aug 14 13:18:08 EDT 2013 Sep 6 12:29:42 controller kernel: Linux version 2.6.32-358.118.1.openstack.el6.x86_64 (mockbuild.bos.redhat.com) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC) ) #1 SMP Wed Aug 14 13:18:08 EDT 2013 Can you confirm that the OVS ports are all untagged? I was assuming so far that is the case but it's not entirely clear based on the information in this BZ. (In reply to Thomas Graf from comment #10) > Can you confirm that the OVS ports are all untagged? I was assuming so far > that is the case but it's not entirely clear based on the information in > this BZ. I don't much understand the question. In the attachment controller_status you can see that there are many ports tagged in in br-int: +ovs-vsctl show 5a53e753-ecea-45e3-8d0e-8cb9db8710bb Bridge br-int Port br-int Interface br-int type: internal Port "tap1ae1918a-71" tag: 3 Interface "tap1ae1918a-71" Port "tapabe9258e-8d" tag: 3 Interface "tapabe9258e-8d" Port "tapa3d1159a-dc" tag: 5 Interface "tapa3d1159a-dc" Port "tap959fdd9b-c2" tag: 1 Interface "tap959fdd9b-c2" ... The question was basically if this is a DUP of BZ997632 which I think is the case. Would you agree with closing this as a DUP of BZ997632?

Hi Thomas, I think you're right --- this is a dup of Bug 997632. Today, I just identified that VXLAN had the issue. So, I'm in the process of identifying at which build we started having this issue. Stay tune. Thanks! Jean Was gre tunnel or vxlan part of the data path? Thanks! Jean (In reply to Jean-Tsung Hsiao from comment #14) > Was gre tunnel or vxlan part of the data path? > > Thanks! > > Jean No. As I drove above, in the bug description, my bare-metal machines have eth1 ifaces interconnected using trunk ports trunking several VLANs. No GRE nor VXLAN. The VLANs are terminated on the bare-metal. This is a duplicate of BZ997632 thus I'm marking it as such in order to keep all the information together. *** This bug has been marked as a duplicate of bug 997632 *** fixed in kernel-2.6.32-358.123.3.openstack.el6 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
