Please use the "Bug" template to file bug reports, so we have sufficient information about your setup. In this particular case the host operation system would be the most important piece missing here.

@jandubois I have made the changes you asked. let me know if this is good or I need to add more info.

Thank you, if you are on macOS, then https://github.com/rancher-sandbox/rancher-desktop/issues/713#issuecomment-1009377616 contains instructions on how to work around this problem.

I didn't realize this bug was in the docs repo; that's why I asked to use the bugs template, but that only exists in the Rancher Desktop repo itself. I'll leave the issue here in docs, because maybe we should add something in the docs until the time when we make this configurable in the UI.

@jandubois Thank you for your response. I followed the instructions. It didn't work for me. I tried looking into this file /etc/security/limits.d/rancher-desktop.conf but I don't see the folder limits.d under /etc/security.

to your compose service
