Template instance limit of '1' reached on cloud

If you get some troubles with docker-plugin, please report
- [ 1.1.4 ] docker-plugin version you use
- [ 2.107.3 on Windows ] jenkins version you use
- [ Docker version 18.03.1-ce, build 9ee9f40 on Linux ] docker engine version you use
- Im connected to the docker daemon using tcp and launching attached on the container and not using ssh
- The containers can connect to the Jenkins server and I am able to do my builds, I am just stuck with one contianer on a server that has been specified to use 100. All the builds us a hybrid image as we have different tools that we needed in one solution.

I built the docker image from jenkins/ssh-slave and only added dotnet, git and nodejs

During the launch I am getting the following:

May 29, 2018 2:23:50 PM INFO com.nirima.jenkins.plugins.docker.DockerCloud provision
Asked to provision 1 slave(s) for: 1362b6c8-1780-4972-a8fe-f325dcd3bfc5
May 29, 2018 2:23:50 PM INFO com.nirima.jenkins.plugins.docker.DockerCloud canAddProvisionedSlave
Not Provisioning 'jnb-dvps-gitlab.sybrin.co.za:4567/root/jenkins-runner'. Template instance limit of '1' reached on cloud 'jnb-dvps-r730'

This happens only when another build is already running using the same image.

Thanks in advance
