The kernel shut down

[Hd-Edison]

When I tried to run

create simulation environment

freq_env = pt.Environment(
wl=1e-6*np.linspace(1.45, 1.65, 1000),
freqdomain=True
)

with freq_env:
# perform simulation
detected = circuit(source=1) # constant source with amplitude 1

# plot detected power
circuit.plot(detected);
plt.show()

in example 00, my kernel just instantly shut down. My ram is 64 GB, so I don't think the problem is here... I wonder if anybody has the same error with me.
