Hi all,
I have a user of TDS who had updated some files on the server and it
seems like TDS is caching this and not refreshing it. Has anyone else
come across this problem?
The directory we're looking at is:
http://opendap-ivec.arcs.org.au/thredds/catalog/IMOS/SRS/SeaDAS/test/
As a test we copied one of the problematic files
(A2009100.0320.L2_OCEANGRID.hdf) and called it test.hdf, and it works
fine! Note that, while the files are identical, the metadata in the
global attributes is different:
new file: time: "2009-04-10T03:22:38Z"
old file: time: "2009-03-10T03:22:38Z"
Interestingly, for A2009100.0320.L2_OCEANGRID.hdf, it seems like there's
problem with the dimensions (which would explain why WCS and WMS doesn't
work). When I tried to retrieve the first 2000 elements in latitude, it
worked fine (I got the ascii response). However, getting 2200, out of a
possible 2437, I get the stacktrace error attached.
I am using version 4.0.26 - 20090831.2140 running on Jetty 6.1.18, with
the following cache settings in TDS:
<DiskCache>
<alwaysUse>true</alwaysUse>

<scour>1 hour</scour>
<maxSize>10 Gb</maxSize>

</WCS>
