Math Domain error in _control.py

[rgerkin]

We have a job that somewhat irreproducibly fails with a MathDomainError on line 55 of _control.py. The argument to the log function there is non-positive for some reason. I don't know if there are supposed to be guarantees elsewhere that this argument should be positive, and why scoop is using a non-positive argument. The error occurs in the middle of some jobs, but not in exactly the same place each time, and sometimes not at all (given the same python files and data). So it appears to be something going on inside scoop.

Can you produce a minimal example?

[rgerkin]

We were never ever able to produce a minimal example -- the error would arise stochastically under identical conditions. It could be architecture dependent. Feel free to close this issue.

We are suffering from the same issue.
Indeed the problem occurs stochastically, preventing us from creating a minimal example.
We are using scoop together with the DEAP package.
