Title:
neutron-keepalived-state-change file descriptor leak
Status in neutron:
Invalid
Bug description:
the https://bugs.launchpad.net/neutron/+bug/1870313 fix the code to
use threading to send garp, well the garp works, but it also
introduced another very seriously bug file descriptor leak!
I tested the train, ussuri branches, both can reproduce the bug, the
reproduce steps is simple, just create floating ip with --port option,
which trigger the l3-agent to configure ip address on qg- interface,
then the neutron-keepalived-state-change will send garp, AND there is
file named "anon_inode:[eventpoll]" left in /proc/<pid of neutron-
keepalived-state-change >/fd.
AS you can imagine, frequently create floating ip and delete floating
ip, what will happen in /proc/X/fd
this could also cause the process neutron-keepalived-state-change
consume huge memory like 10G+
