The conditions cited in 12.13 were not reported by the parent or any of
the sibling caches.

There was, however, an unusually high occurance of 50x status recorded in
the access log, in particular, 503 and 504 statuses. Typically, the total
number of these codes averages less than 5000 per month. So far this
month the total has exceeded 90000 occurrances. The principal source of
the errors seems to be Yahoo! web sites.

I presume this is the trigger event?
