Yea, adding the appropriate close methods did not make a difference.
Here is the loop I am running:
*foreach(String curGroup3Name in curGroup3Names)
{
H5FileId hdfFile = H5F.open(pathToHDF, H5F.OpenMode.ACC_RDONLY);
H5DataSetId curDataset = H5D.open(hdfFile, curGroup1Name + "/" +
curGroup2Name + "/" + curGroup3Name + "/dataset");
float[] curDatasetArray = GetDatasetArray(curDataset);
H5D.close(curDataset);
H5F.close(hdfFile);
MessageBox.Show("Finished dataset for tile " + curTileName + "...");
}*
Just as in my other code, I get to about the seventh iteration and i
hangs on the call to:
*H5D.read(dataset, datasetNativeType, new H5Array<float>(dArray));*
...that happens inside the method getDatasetArray(curDataset). That
code is listed below...
Any ideas anyone?
Thanks again,

Hey, Scott. Yea, I caught that after I sent the e-mail. I am writing
a test program now. I will let you know if that solved it.
Thanks,

Hey Donald,
You need to be close()ing your H5T type objects. I'm not sure if
that's it, but....

*Subject:* [Hdf-forum] memory issues when reading multiple datasets
Hello all:
I have another problem that I could use some help with. In a
nutshell, I have multiple datasets that I am trying to read arrays
from and then work with those arrays one by one. The structure of
the .h5 file kinda look like this:
*Group<root>
Group<Group1>
Group<GroupA>
Group<Group_a>
Dataset<1>
Group<group_b>
Dataset<1>
Group<GroupB>
Group<Group_a>
Dataset<1>
Group<group_b>
Dataset<1>
Group<Group2>
Group<Group_a>
Dataset<1>
Group<group_b>
Dataset<1>
Group<GroupB>
Group<Group_a>
Dataset<1>
Group<group_b>
Dataset<1>*
I am recursively going through each group and then executing code
that looks something like this:
* public float[] GetDepthArray(H5DataSetId dataset)
{
H5DataTypeId datasetType = H5D.getType(dataset);
H5T.H5TClass datasetClass = H5T.getClass(datasetType);
H5DataTypeId datasetNativeType =
H5T.getNativeType(datasetType, H5T.Direction.ASCEND);
long storageSZ = H5D.getStorageSize(dataset);
float[] dArray = new float[storageSZ];
H5D.read(dataset, datasetNativeType, new
H5Array<float>(dArray));
return dArray;
}*
After about the seventh iteration, the code will fail with an
AccessViolationException - "Attempted to read or write protected
memory. This is often an indication that other memory is corrupt."
Anyone have advice as to whether or not I should be cleaning
something up after each iteration that I am not seeing? My system
RAM seems to be un-phased after each iteration so at least it doesn't
look like I am losing memory anywhere...
Thanks for the help!
