Segmentation Fault seen on the Matlab2021b docker container

[Rakshan-PK]

Hi,
We are using the matlab docker file with the same structure as seen on the main branch. We are using version : 2021b.
Additionally, we have configured the container with the following products :

So whenever we execute matlab commands, we have a weird behavior. We see segmentation fault with the following error log.

Could not create on-disk crash report: failed opening file: No such file or directory: iostream error

MATLAB is exiting because of fatal error
Killed
[Pipeline] echo
generateStatus  : 137

Workarounds tried:
Increased memory : --shm-size=2G to 4G to 8G ( No success)
Came across this link : and tried

keeping in mind the installation path inside my container. Still no success.

Would be of great help if you could suggest a solution.

Hi @Rakshan-PK ,

Thanks for reaching out.

In order to be able to reproduce this issue, could you please share with us:

• your Dockerfile
• the command that you are using to build the docker image. Are you just running docker build .?
• the docker run command that you are using to start the container
• the MATLAB command that gives this error

Thanks and regards

To give an overview of our process, yes we have matlab image built on our VM. From the jenkins pipeline, we execute jobs on this image(which runs the matlab container)

• Our dockerfile: Attached

• The build command : docker build -t <tagname> .

• The docker run command comes from Jenkinslogs :

docker run -t -d -u 1000:1000 --shm-size=2G --mac-address=XXXXX -e MLM_LICENSE_FILE=/opt/matlab/licenses/license.lic -w /var/jenkins_home/workspace/test--volumes-from b1335b344f794211c02188da3ddec7f2b1c66bb6bd01aee6ce7830d235641828 -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** matlab21b-v2 cat

Hi @Rakshan-PK ,

We have not been able to reproduce the issue following the provided instructions. Could you please confirm whether:

1. You can reproduce the issue on a local machine (instead of the Jenkins pipeline)?
2. You can reproduce the using the latest version of our Dockerfile with no changes except build arguments?
3. You are using a proxy registry with an old matlab-deps?

If you find the same issues with all the above then could you please confirm whether:

1. it crash for all models?
2. it only crash when loading models and using Simulink? What about any other MATLAB code?
3. it is possible to use a newer version of MATLAB?

Thanks and regards

[Rakshan-PK]

Hi, apologies for my late response
Answering your questions:

1. The jenkins pipeline is currently hosted on a remote server. Its a headless server. So, executing it on the server(debian VM) directly without Jenkinspipeline is something I have not tried. However, the same model builds perfectly on a WIndows machine
2. We currently use 2021b. Does the latest version of dockerfile mean the latest matlab version as well? Currently we just use 2021b.
3. No, we do not use proxy registry

Hi @Rakshan-PK ,

Unfortunately, we have not been able to reproduce the issue on our end yet. The issue might be due to several possible causes, including:

• the mathworks/matlab-deps:r2021b base image being outdated,
• the fact that you are not using the Dockerfile that we have provided in this repository.

To narrow down the list of possible causes, could you please try building a Docker image from the Dockerfile provided in this repository and use it in your Jenkins pipeline?

To build the Docker from our Dockerfile you can:

git clone git@github.com:mathworks-ref-arch/matlab-dockerfile.git
cd matlab-dockerfile
docker build --no-cache --pull -t repro:r2021b --build-arg MATLAB_RELEASE=r2021b --build-arg MATLAB_PRODUCT_LIST="MATLAB Simulink MATLAB_Coder Simulink_Coder Embedded_Coder" .

The --pull and --no-cache flags will make sure that you are using the latest version of the mathworks/matlab-deps:r2021b base image, and the MATLAB_RELEASE and MATLAB_PRODUCT_LIST build arguments will install the selected products and release.

Then, you can use the image repro:2021b in you pipeline. We have tried running the image via:

docker run -it --rm -v  <path/to/license/file.lic>:/opt/matlab/r2021b/licenses/license.lic -e MLM_LICENSE_FILE=/opt/matlab/r2021b/licenses/license.lic repro:r2021b

and, then, executed load_system('A_Model') in the MATLAB Command Line but it did not result in a crash.

Could you please:

1. Try the steps above?
2. Use the repro:2021b image in the docker run command you provided, instead of the matlab21b-v2 image?

Thanks and regards
