Render process break down without error.

[saprrow]

Describe the issue

I am using multi-processing to render data. Each process renders 25 images for 200 scenes, so one process should render 5000 images at all. But almost half processes only rendered about 3000 images and then broke down. I rendered at a sever with sufficient computering powers. So it shouldn't be the device's issue.

Below are some logs of processes broke down. They just stoped rendering without error logs.

And here is the log of processes run normally.

I truely appreciate it if someone could help me!

After pulling this commit fixing #1083 and increasing the open files limit by ulimit, this issues seems be solved.

Thanks for the bug report. This should be fixed by #1084.
The fix is now also part of the new blenderproc version 2.7.1
