On a single program that I'm running algorithm type genetic, I'm seeing the following exception occur a few times:
<title>requests.exceptions.ConnectionError: ('Connection aborted.', OSError(24, 'Too many open files')) // Werkzeug Debugger</title>
I captured the STDOUT to a debug.log, so if this is something that is of interest to debug, I can attach that log.
errata: I have a large population size and number of generations that probably contributes to the expression of this error:
algorithm:
type: genetic
population: 200
generations: 200
tournament-size: 20
mutation-rate: 0.8
crossover-rate: 0.4
# look at entire test suite for test sampling [subset of testsuite is 100%]
test-sample-size: null
Looks like this ConnectionError ultimately results in the darjeeling process to hang. I'm guessing that it's waiting for evaluation data from the lost Candidates.
