bblfsh spawns zombie processes when it runs on ubuntu

[zurk]

What happened?

I worked with bblfsh on science-3 machine and found that too many zombies spawn in the system.
when I close bblfsh container they are gone away.

How can you reproduce it?

I work with bblfsh on science-3 machine.
It will be easier to reproduce it on it (In case, I can show you how) but in general, I do something like this:
run bblfsh in the usual way
docker run --privileged -p 9432:9432 --name bblfsh bblfsh/server

run another container in my case it is
docker run --rm -it -v /storage:/storage --device /dev/nvidiactl --device /dev/nvidia-uvm -v /data:/data -expose=9432 --privileged -e "LD_PRELOAD=" srcd/science bash

May be it is reproducible just in the system.

then

pip3 install git+https://github.com/bblfsh/client-python
pip3 install git+https://github.com/src-d/ast2vec@develop

and then run attached script.
entry_point.py.zip

You can check kind of zombies number with ps aux | grep Z | wc -l before and after.
In my case it 4 and 15.

Priority:

Medium

I need to get UAST for many repos in nearest future, so it quite important.

Other info you may need:

I tried to reproduce the same result under MacOS and failed

I'd say it's a duplicate of #42

[zurk]

Seems to be.
Can you estimate when it will be fixed?

@zurk I'll close this, let's move the discussion to #42 to avoid duplication
