both tests show pass but the "hdfreader error" is concerning.
Is check_stats.py not robust? Probably not checking file operation(open/read) status?

What is the Python environment on the machine in question? Do you see this error elsewhere?

[ye-luo]

It is Ubuntu 22.04.4 OS provided python and h5py.

[jtkrogel]

Please post the output from the following:

>python3
>>> import h5py
>>> h5py.__version__

[ye-luo]

Got '3.6.0'

I fixed the false negative issue #4998 and exposed the failure on multiple CI nodes.

[ye-luo]

Good news is that #4991 failed for unrelated reasons.

All the failures in the CI runs of #4998 use ubuntu 22.04
