I'm currently getting the error on a call to cg_section_write:
cgio_write_all_data:H5Dwrite:write to node data failed
when writing 137M tet cells in serial (so 137M * 4 = ~548M array of size_t's). The same code works perfectly well with smaller meshes.
I'm using CGNS 3.4.0 compiled with --enable-64bit and --enable-lfs, with HDF5 1.10.5 (which I believe by default compiles with large file support, although i shouldn't be hitting that limit anyway.)
This code seems pretty benign – are there any related known issues, or a suggested way to go about debugging this?
