I also get an 'array out of bounds exception' sometimes, but it continues and eventually generates a model

from h2o-tutorials.

And I'm starting to get this often, when generating model after model in the same console. These commands below kinda help, but I still have to monitor for every crush. What might be a specific root cause? The resources are OK, enough memory and everything.
taskkill /F /IM "python.exe"
taskkill /F /IM "java.exe"
