Subject: [opencontrail-dev] Kernel panic when doing `iperf -M 90`
Hi, we saw the attached kernel panic message on the screen when we ran `iperf -M 90` between two VMs on different hosts. Please let us know what log you need to help debug this.
Our setup is pretty simple. We have three servers running devstack with 1 of them being the contoller, and the other two being compute nodes. There's only 1 VM setup on each compute node, and we are doing TCP iperf. The MTU is 9000. iperf -M 1480 works fine. But, 90 bytes leads to kernel panic repeatedly.
