---------------------------------------

             Summary: Docker Image guacamole/guacamole won't start - Cannot create VM thread. Out of system resources.
                 Key: GUACAMOLE-1693
                 URL: https://issues.apache.org/jira/browse/GUACAMOLE-1693
             Project: Guacamole
          Issue Type: Bug
          Components: guacamole-docker
    Affects Versions: 1.4.0
            Reporter: André Müller


When I start the guacamole/guacamole Docker image with the command:
{code:java}
sudo docker run --name netzgrenze-guacamole --restart unless-stopped --link netzgrenze-guacd:guacd -e MYSQL_HOSTNAME=10.201.240.120 -e MYSQL_DATABASE=guacamole -e MYSQL_USER=<dbuser> -e MYSQL_PASSWORD=<password> -d -p 8080:8080 guacamole/guacamole{code}
it will keep restarting. I've looked at the logs, and they say
{code:java}
Error occurred during initialization of VM
Cannot create VM thread. Out of system resources. {code}
When I enter the Container with sudo docker run -it guacamole/guacamole shell and start java I'll get the same output:
{code:java}
guacamole@ba8c3c820f3d:/opt/guacamole$ java
Error occurred during initialization of VM
Cannot create VM thread. Out of system resources.{code}
I deleted all Container and Images of guacamole/guacamole and pulled it again, but there was no change. The System is Ubuntu 18.04.6 LTS, and it has 4GB of Ram, with plenty of free Ram:
{code:java}
