Can you find out what kinds of file descriptors are open? Are they
sockets (and what kind), etc.?
This could be a file descriptor leak of some kind. If it is, then
restarting OVS would fix it; if it is not, then restarting OVS will not
help, or at least not for long. Can you figure out whether restarting
reduces the number of file descriptors, and by how much?
