===== UPDATE 11/10 ====== hi again, based on some advice from a member of this mailing list we've been looking into kernel and driver versions of our compute nodes
We also have plain non openstack "KVM on Ubuntu" servers for testing. I looked at driver and kernel differences between these Ubuntu 16 w/ KVM systems and our openstack compute nodes. I found Ubuntu 16 w/ KVM was at kernel version 4.4.0-87 and that the openstack compute nodes were at 4.4.0-93. So I upgraded the Ubuntu 16 w/ KVM to 4.4.0-93 and was able to reproduce this problem (but only on the exact HP hardware that is our openstack compute nodes, and not on other hardware). Next I updated these Ubuntu 16 w/ KVM to 4.4.0-98 and the problem no longer occured! I need to upgrade a few openstack compute nodes to 4.4.0-98 and test. Do anyone think this kernel change could break openstack? In the kernel change log I found a fix for a specific HP server in 4.4.0-98 (not the same as our server but somewhat similar) thanks! -- Jim On Mon, Oct 23, 2017 at 10:25 PM, Jim Okken <j...@jokken.com> wrote: > ===== UPDATE 10/23 ====== > > we have been trying different things to get better debug we disabled > rate-limiting in order to get better info in /var/log/message. for some > reason (maybe unrelated) we didn't get the soft lockup during this test But > this time we got openvswitch, br_netfilter, etc in the call trace in > /var/log/messages > > Please advise in any way! thx!! > > basically we are running various types of SIP/RTP test traffic between 2 > instances (on different compute nodes).
