Mike Jumper closed GUACAMOLE-1693.
----------------------------------
Resolution: Invalid
At the stage that you're seeing this error, Guacamole has not run, nor is there
anything about the JVM that is specific to the Guacamole Docker image.
My guess would be that your system has exhausted some other limit, perhaps the
upper limit for number of threads or file descriptors. Regardless: not an issue
with Guacamole nor the image itself.
> Docker Image guacamole/guacamole won't start - Cannot create VM thread. Out
> of system resources.

> 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
> Priority: Critical
>
> 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}
