WavePy is a Python 3.12-based ocean wave data processing system running in a Conda environment called wave312. During recent development, the process started vanishing without warning. No Python traceback, no error logs, just gone.

The last line of the log always stopped at the memory monitor output for scipy.interpolate.griddata:

2026-03-02 01:23:43,251 - MemoryMonitor - INFO - [MEM][interpolate_unstruct_grid:hsig:20260302_060000] RSS: 1440.44 MB

After that, nothing. No traceback, no exception. It was a classic C extension segfault.
