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!
