Hi Team, We are currently facing ovs-vswitchd crash and restart every one hour. Currently, we are running the following versions on hypervisor. Here is the version info and the backtrace of the core below. This is addressed using https://github.com/openvswitch/ovs/commit/106ef21860c935e5e0017a88bf42b94025c4e511
https://github.com/openvswitch/ovs/commit/111c7be3193e15e2acf8af8ceb74a1177a95806d. It has been validated. To take advantage of this fix and other performance improvement fixes, We want to migrate to OVS 3.x version. When it comes to version compatibility with ovn-controller and OVS DB schema, What are the compatible versions, if we want to migrate to OVS 3.x version? # ovn-controller --version *ovn-controller 22.09.2* *Open vSwitch Library 3.0.3* OpenFlow versions 0x6:0x6 SB DB Schema 20.25.0 # ovs-vsctl --version *ovs-vsctl (Open vSwitch) 2.17.6* *DB Schema 8.3.0* Using host libthread_db library "/lib64/libthread_db.so.1". Core was generated by `ovs-vswitchd unix:/var/run/openvswitch/db.sock -vconsole:emer -vsyslog:err -vfi'.
