Description

This is a regression from 0.9.0 and happens with 0.10.0 with Python 3.6.5 on Linux.

from pyarrow import plasma
import numpy
import time
import subprocess
import os
import signal

m = numpy.matrix(numpy.array([[1, 2], [3, 4]]))

process = subprocess.Popen(['plasma_store', '-m', '1000000', '-s', '/tmp/plasma', '-d', '/dev/shm'], stdout=subprocess.DEVNULL, stderr=subprocess.DEVNULL, encoding='utf8', preexec_fn=os.setpgrp)
time.sleep(5)
client = plasma.connect('/tmp/plasma', '', 0)

try:
    client.put(m)
finally:
    client.disconnect()
    os.killpg(os.getpgid(process.pid), signal.SIGTERM)

Error:
