      Description

      After running CHO (ATT topology) for two days, when we do the following loop:
      install intents -> bring down link -> pingall -> bring up link -> uninstall intents
      It is very frequent that intent rerouting after link down becomes slow. Flows are not updated for several minutes.
      Specifically, e.g. after link s1-s2 down, intents are all in INSTALLED state and there are no pending_add flows, and paths is also updated, but flows toward s2 on s1 still point to the disabled port.

      Some system information on ONOS nodes:
      Note that in CHO test the system load keeps increasing along with the growing traffic (see attachment). Tshark summary shows the major traffic are from and to port 9876.
