Hi John,
Some of my aggregations are updated with a new file daily but others
are more permanent. Because of the daily updates, I need to keep my
scour set to every 24 hours. However, the dataset that is more
permanent (our tide model, which has forecasts out through the end of
2011) is the one causing me the recurring slowness. Even though the
files in that dataset have not been updated since late November nor
have any new files been created, it is still taking several minutes to
access the OPeNDAP URL on what seems to be a daily basis, though I'm
still trying to tease out what the pattern is. The file for that
dataset gets re-written in the content/thredds/cache/agg folder when
this happens. It'll be fine for a day, but then by the next day it's
usually slow again on first access (~5 minutes to access the OPeNDAP
page). It would appear that the scour is happening regardless of my
30-day maxAge setting? Don't know what else I can send you to help
troubleshoot; lemme know... In case it helps, here are the datasets
that are causing me this problem:

Hi John:
An aggregation that updates daily should never get scoured. The scour is
really about keeping the cache directories from filling up with old stuff.
Send me the following:
1) thredds/content/logs/cache.log
2) thredds/content/cache/agg/*
3) the config catalog that contains tide_mod.xml
