Hi there,
I am trying to aggregate netcdf files for some rather large datasets
with tomcat6.0.36/TDS4.19 - 20131008.1358 and am running into a "Too
many open files" error.
My catalog scan is:
<dataset name="ASR 30 km 2d surface analysis"
ID="ds631.0_anl_2d-AGG"
urlPath="ds631.0/9/best"
harvest="true">
<serviceName>all</serviceName>
<netcdf
xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";>
<aggregation dimName="time" type="Union">
<scan location="/glade/p/rda/data/ds631.0/asr30km.anl.2d/"
suffix=".nc" subdirs="false"/>
</aggregation>
</netcdf>
</dataset>
which contains about 4020 files and totals 470G.
The message that the server sends when trying to access the OPeNDAP
service is:
Error {
code = 404;
message = "/glade/p/rda/data/ds631.0/asr30km.anl.2d/asr30km.anl.2d.20010619.nc
(Too many open files)";
};
When trying the CdmRemote service catalina.out repeatedly reads:
Oct 24, 2013 11:20:39 AM org.apache.jk.common.ChannelSocket
acceptConnections
WARNING: Exception executing accept
java.net.SocketException: Too many open files

The cache settings in my threddsConfig.xml are the default settings.
Have I overlooked something?
