[I trimmed the config to nothing -- no zones, just a log and
caching for the local subnet. It's behind a firewall, so it's
completely idle. I fired it up with "-f -d 3 -u <userid>". I'll do
it again just for the heck of it, but it appears to spike at one
hour, following "database: debug 1: cache cleaning timer fired,
cleaner state = 0". A small set of log lines repeats hourly (I can
post them if it'll help), as there is (deliberately) no activity...]
Bah! What am I, helpless? While I was waiting, I read the manual,
and adjusted the intervals in a short stagger. The "interface-
interval" (which logged nothing, even at debug 3) was the culprit,
which is good -- I can kill it. I did, and I'll post again in a few
minutes if that's really it. Hmmm... Come to think of it, I'll let
it go for a few hours.
Hey, I got a reasonable test of my thermal solution, without having
to install Prime95...
Comments? I can possibly help with it, but I don't want to thrash
my server -- I need to get it into production one of these days.
