I have double checked and the server has not been restarted since January 3rd
at 3pm. The server does not restart without my manually controlling it, so
there shouldn't be any restarts that I'm unaware of. Thank you for looking into
a possible bug. Would it help to add a "recheckEvery" attribute? Another piece
of the puzzle I discovered this morning while poking through my logs:
2011-01-03T15:03:38.619 -1000 [ 934][ 1] ERROR -
thredds.servlet.ThreddsConfig - ThreddsConfig: param AggregationCache.scour
not udunit time Can't convert from unit "-1.0" to unit "s"
Apparently it does not like <scour>-1</scour>, despite what I read in the
documentation. Could that be the problem? Maybe only part of the problem, since
I've removed AggregationCache entirely in previous tests and still get
recurring slowness. Lemme know...
Thanks!,
John Maurer
