HDF5 Error about synchronously create file

[ErenC1]

Hi!

I am getting the following error in a specific geometry (and only with this geometry, it is a capillary). I tried to re-mesh and re-export this geometry as ASCII, Binary, checked geometry for every problem and nothing seems to be wrong. But the error persists.
Simulation does not crashes, it still writes the hdf5 files of the fluid and the RBC. RBC data looks good, but fluid data doesn't seem correct (it scatters A LOT) and I'm wondering if this error is somehow related with it or not.

Note: PreInlet bounding box is different than the main domain bounding box. Could it be a reason for this? (never had problem with it before)

I looked into hdf5 forums, but I don't want to break something else while working on it.

I'm using cmake 3.24.4, gcc-7.5.0, python 3.76, openMPI 4.16, HDF5 1.143.

(error continues in each time-step with:
