Description

From issue #1302, it appears autosklearn is a bit unstable when run many times in the same script, i.e. in a for loop.

for i in range(400):
    automodel = AutoSklearn(full_resources)
    automodel.fit(x, y)

We currently have no test for this and it would be good to see if we can reproduce the same connection refused error.

Contributor guide

Research direction
Create a script that repeatedly constructs and fits AutoSklearn models in a loop. Monitor for 'connection refused' errors. Investigate resource leaks or server port conflicts.
