In the last 12 hours, we've had repeated instances of named getting
wedged. The symptoms are:
* named consuming nearly 100% CPU, all in user-time
* lots of queries apparently not processed, and based on query
logging, a sharp drop in the rate of queries that are
* a very sharp drop (almost a complete halt, in fact) in the rate of
RPZ "hits" in the logs at the exact time this happens
* no other interesting logs, as far as I can see
Re-starting the named process clears it.
I can't see anything in the release notes for 9.8.4/9.8.5 - any ideas?
This is with the Spamhaus DBL, in case it matters.
