I'm trying out the example code from https://www.mathworks.com/help/5g/ug/nr-cell-search-and-mib-and-sib1-recovery.html from a remote ubuntu desktop through anydesk. At the same time I tried to edit the code inside vscode via ssh. The system load is not very high at most 2 and only use about one or two cores at the start, even I'm running the examples.
But after I have leave everything running there for quite a long time. There will automatically spawn a lot of InstallMathWork process, and the number of processes is gradually increasing. Eventually, it will have a lot of InstallMathWork process running in the background and eats up all the CPU cores, the system load increase to very high eventually.
I have checked that I'm already updated to the latest version manually and checked there's no newer versions available. My current matlab version is R2024a Update 2 (24.1.0.2578822) 64 bit (glnxa64) April 9, 2024
Below is the screenshot from top and htop.

Hey shijie,
I have recently faced a similar issue while working on my linux desktop (Ubuntu 22.04). I noticed that the versions of MathWorksServiceHost and MathWorksServiceHost installer did not match.
I have tried deleting the following directory:
~/.MathWorks/ServiceHost/$HOST
This workaround has resolved my issue.
If the issue persists, try reinstalling MATLAB or reaching out to MathWorks Technical Support: https://in.mathworks.com/support/contact_us.html
I hope this helps!
