Hi Nicolas,
We delete old data regularly on our server as well. We are not seeing
this problem, though most of our heavily used datasets are handled with
featureCollection rather than datasetScan configurations. I am at a
meeting all week but will try to take a closer look at the datasets we
do serve using datasetScan in the next day or so. (The rest of the
THREDDS developers are out this week as well. Sorry for the delay.)
We have never tested the TDS with openjdk. You could try running your
server using Oracle's JRE and see if that makes any difference.

Dear
I'm keeping several days archive on my server.
Every time a new run is issued, I delete an older one.
When I do "rm" on the older files, it's no longer shows up with "ls".
However TDS is keeping the file busy, and disk space is not freed.
I can see this thanks to "lsof"
$ lsof

To free disk space, I need to restart tomcat.
So, is there a way to notify THREDDS a dataset will be deleted, so it
closes the files before deletion ?
I'm using TDS 4.3, with tomcat 7, openjdk, over ubuntu 12.04 x64.
Dataset configuration :
<datasetScan name="RASP" ID="rasp" path="rasp"
location="/home/upload/data/">
<metadata inherited="true">
<serviceName>all</serviceName>
<dataType>Grid</dataType>
</metadata>
<filter>
<include wildcard="*.nc"/>
</filter>
</datasetScan>
can be seen there : http://data2.rasp-france.org/thredds/
