Public bug reported:
Similar to bug 1570466 but a different root cause.
It was identified that memory leaked on continuously adding/removing vhost_user
ports in openvswitch-dpdk.
See the other bug for reproduction suggestion.
Fortunately for this bug a fix is already upstream in the openvswitch
2.5 branch.
In particulr for this bug we need:
d9df7b9206831631ddbd90f9cbeef1b4fc5a8e89 netdev-dpdk: Fix memory leak in
netdev_dpdk_vhost_destruct().
But there are more critical ones related to openvswitch-dpdk:
a39aa7e10d033e3ed15b16bd101f655aa1db8135 dpif-netdev: report numa node number
on pmd thread create failure
e099c86ca432d1daeaf8edb66225e7edf061c0b0 netdev-dpdk: vhost: Fix txq enabling
in the absence of notifications.
3b70d8fcca23d9fed2f2a2c2e9eb428e4a202123 netdev-dpdk: Fix crash when changing
the vhost-user port.
f61053debcb466d8bfec31070f0826e3c0e3c727 INSTALL.DPDK: remove issue with QEMU
v2.4.0 and dpdkvhostuser
05a00f12f2c4e25077f0ca55f7f6734908932abf netdev-dpdk: fix mbuf leaks
I understand we generally wait for the 2.5.1 release which will get some
extra test and checks, but I hope that shouldn't be too far away.
So please merge the 2.5.1 point release of openvswitch as soon as
available to fix this issue.
