Description of problem:

docker exec command on Ubuntu container is failing.

However, it works fine on CentOS container inages

Version-Release number of selected component (if applicable):
docker 1.13.1-84.git07f3374 (RPM version i.e. rpm -qa | grep docker)

How reproducible:

Always

Steps to Reproduce:
On RHEL 7.6 run following commands

1. docker run -ti --rm ubuntu bash
2. Open a new tab 
3. run the "docker ps" command and note the container ID for the Ubuntu container
4. Run "docker exec -ti <Container ID> bash"

Actual results:

$ docker exec -ti 015c6ad3c816 bash

rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:247: starting container process caused "process_linux.go:110: decoding init error from pipe caused \"read parent: connection reset by peer\""




Expected results:

docker exec command should run without any issue

Additional info:

The issue is coming with docker 1.13.1-84.git07f3374 (RPM version), but we cannot reproduce the same issue with docker 1.13.1-75.git8633870. 

We got this while testing latest CDK build based on latest RHEL 7 : https://issues.jboss.org/browse/CDK-380
