Public bug reported:

I left my DevStack env for a several days to see the following:

stack@mdulko-devstack-ovnvm-0:~$ free -m
              total        used        free      shared  buff/cache   available
Mem:          16039       15407         132         375         499          22
Swap:             0           0           0                     

htop confirmed me that this is o-api taking that and restarting it
helped immediately:

stack@mdulko-devstack-ovnvm-0:~$ sudo systemctl kill devstack@o-api
stack@mdulko-devstack-ovnvm-0:~$ sudo systemctl restart devstack@o-api
stack@mdulko-devstack-ovnvm-0:~$ free -h
              total        used        free      shared  buff/cache   available
Mem:            15G        8.4G        6.3G        375M        1.0G        6.7G
Swap:            0B          0B          0B

This was an env running kuryr-kubernetes that happened to have a bug
that kept setting the listener timeouts for the LB all the time. I guess
this might have had contributed to the problem.
