Description of problem:
When I send signal 27 to the docker process, which is running with
--sig-proxy=true, it's not forwarded. Other signals are...
Version-Release number of selected component (if applicable):
docker-0.10.0-8.el7.x86_64
docker-io-0.9.1-1.fc21.x86_64
upstream Docker version 0.10.0, build dc9c28f/0.10.0
How reproducible:
always
Steps to Reproduce:
1. /usr/bin/docker -D run --tty=false --rm -i --name test_eoly
localhost:5000/ldoktor/fedora:latest bash -c 'for NUM in `seq 1 64`; do trap
"echo Received $NUM, ignoring..." $NUM; done; while :; do sleep 1; done'
2. ps ax |grep docker
3. kill -27 $PID
Actual results:
nothing
Expected results:
Received 27, ignoring...
Additional info:
When you send any other signal (apart from 19 or 9) it works fine.
