If you look at the 1400 sample for today, the lat lon are shifted. Can you let me know if you can check it out?

The upgrade seems to working no problem, but my threddsServlet.log hasn't updated since March 30. Is this something that only updates when there is an error? Or should it be updating often?

I've upgraded to 4.2.5 and will take a look at the errors later today.

There are some errors happening
ERROR - ucar.nc2.ncml.Aggregation - Cant make cache directory= /usr/share/tomcat6/content/thredds/cache/agg/HFRNet-AKNS-6km-hourly-RTV
that are fixed in the latest version of 4.2.5
Can you upgrade and see if its still happens?

gather before I empty the cache?
Any other info you have would be appreciated.

1) what version TDS?
2) is this an aggregaton? (you can send me the config catalog)
yes, threddsConfig.xml& catalog.xml attached, let me know if you want
more (we have an enhancedCatalog.xml and wmsConfig.xml too)
3) are there errors in threddsServlet.log?
yes, I've attached a text file with the errors from the logs
4) when you "update the netcdf files multiple times over 5-6 hours ", do you
I believe the the files are always overwritten. I'll double check and
get back to you if I'm wrong.
its hard when its intermittent, we may have to figure out how to

An example of bad data being served through THREDDS: we are working
with ASA& USCG to get data into their SAROPS product. They have
complained that many of the data samples have had data in the wrong

this as well using the Godiva viewer, and when I compare the Godiva
map with the source netcdf file, it is not plotting the data in the
correct location. This makes me think it is a problem with the data

typically update the netcdf files multiple times over 5-6 hours after
they are created. I'm not sure if the updating of the netcdf files is
the cause of the problem, but it is not something that is easy to
The problem we have with weird timestamps happens occasionally, and in
random locations throughout the time index. It usually is just one
sample here or there, and not successive samples. It almost always
goes away when I empty the cache.
I'm not sure if these issues are setup related, or issues we can
script some workarounds to help. But I wanted to check with you to see
if you have any idea of what is going on.
