Openvswitch: large packets are getting dropped
Issue
- TCP connections from external hosts hang due to dropped packets - appears to be an
MTU
issue (with incoming large packets being dropped) except that setting a lowMTU
(1200) on both ends of the connection doesn't fix the problem. Outbound large packets work fine. Connections from the network controller work fine.
Environment
