Behaviour observed for both standards, FMI 2.0 and 3.0
If I have an FMU with a high number of ports of the same data type defined, it hangs.

Initially I thought that the limit was 124 ports of the same type, but the more I've tested, I observed this is not really consistent.
Nevertheless, with something like 140+ ports, it always hangs

FMU 2.0 with 140 outputs that hangs

Update: FMU tested with fmpy and it works
