I'm writing a model that needs a lot of random numbers. The model counts up to "Year:640: Count:1339" (taking around two minutes) and then hangs on random.uniform(0, 1). While it hangs, the amount of RAM python takes grows till it eats up all available RAM with RAM usage growing by around 100 MB per second.

I'm running Windows 10 and the error appears in both Python 3.8.8 as well as in 3.9.5. I'm attaching a file that reproduces the error. 

File "C:\Users\Christian\folder\obfuscated.py", line 427, in <module>
    population = population.next()

  File "C:\Users\Christian\folder\obfuscated.py", line 385, in next
    return Class4(self.nextClass4)

  File "C:\Users\Christian\folder\obfuscated.py", line 280, in __init__
    var42.var30()

  File "C:\Users\Christian\folder\obfuscated.py", line 177, in var30
    var22.var30(self.var17,self.var18,self.var21)

  File "C:\Users\Christian\folder\obfuscated.py", line 100, in var30
    self.barClass1s.append(var23.child())

  File "C:\Users\Christian\folder\obfuscated.py", line 29, in child
    if var6>random.uniform(0, 1):

  File "C:\Progs\anaconda3\lib\random.py", line 417, in uniform
    return a + (b-a) * self.random()
