Hello all,


I am experimenting with a 3 nodes community edition installation using Virtualbox, each node running on CentOS 6.8, all went smoothly until 95% (Configuring second stage files) where the errors are:

- error: can't start new thread

- IOError: [Errno 32] Broken pipe


Memory for each node is 8GB, most ulimit settings (such as max user process) are already unlimited, I have tried quite a few things but really can't fix it


Some info captured from log

Would appreciate if you can share some suggestions for further troubleshooting.
