OK, that looks like it then; this isn't one of the spiders crawling
through *all* patches (and does seem to be contained to OVS & OVN) but
it's certainly a major contributor to load.

It seems to be re-requesting the same view hundreds of times. From one
day's worth of log, the top 10 URLs from that IP:
   
       399 /api/patches/1887072/checks/
       285 /api/patches/1888116/checks/
       285 /api/patches/1888115/checks/
       285 /api/patches/1888111/checks/
       228 /api/patches/1888114/checks/
       228 /api/patches/1888112/checks/
       228 /api/patches/1887464/checks/
       228 /api/patches/1887463/checks/
       228 /api/patches/1884952/checks/
       228 /api/patches/1884950/checks/

- totalling 43,786 requests for that day.

I can send you a log over a day if that's helpful.

Cheers,
