John,
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?
Hi Tom:
threddsServlet.log should get new messages every time a request
comes in. If thats not happening:
stop server.
remove/copy all files from {tomcat}/logs and
{tomcat}/content/thredds/logs
restart the server
and make sure its starts to update. if still not happening, send me
all the content of both directories.
its probably a good idea to clan out those logs, so that old
messages dont confuse us as we try to debug this problem.
Thanks,
Tom

Hi Tom:
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?

HI John,
I was wondering, when I see this again, what
files and logs should I
gather before I empty the cache?
Any other info you have would be
appreciated.
Thanks,
Tom

Hi Tom:
1) what version TDS?
Version 4.2.1 - 20101201.2028
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
overwrite? extend?
I believe the the files are always
overwritten. I'll double check and
get back to you if I'm wrong.
THANKS
Tom
its hard when its intermittent, we may
have to figure out how to
consistently reproduce.

HI John,
I have been tasked with maintaining
the HF Radar national network
THREDDS server here at SIO. Rich has
helped us set things up, and has
been a valuable resource for learning
this system. We have been having
a frequent problem that Rich has been
unable to help us with, which is
occasional bad timestamps and
occasional bad data served through
THREDDS.
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
geographical location (ie ocean
currents over land). I have noticed
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
being served by THREDDS. The problem
goes away after some time, as we
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
reproduce.
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.
Thanks for your time,
