zsh: abort      cargo run --release --example publish_subscribe_subscriber

Expected result or behaviour:
Expected to see the subscriber start and receive a message (assuming I run the publisher example as well)

Conditions where it occurred / Performed steps:
Happens on every run of the publish_subscribe example.

[elfenpiff]

@bschwind could you please try it in debug mode?

[elBoberido]

@bschwind I don't have a mac to test but it seems you have a ludicrously fast device. Can you try #82 and check if it fixes the issue for you?

[bschwind]

Here it is in debug mode:

@bschwind I think you hit one of the open issues of iceoryx2, meaning when a process crashes we do not yet have an instance that cleans up stale resources. Could you reboot your mac and try again, please? On linux you can do a simple sudo rm -rf /dev/shm/iox2_*; sudo rm -rf /tmp/iceoryx2/services/* but on mac os it is not that easy since the shared memory is not accessible via the file system.

I see, thanks for the info! Sorry to bail for now but I'm in the Japan timezone and about to sleep 😅

I'll report back tomorrow with what happens after a reboot.

You know what, I think I made a stupid mistake on the last check - I'm running the subscriber twice, instead of a subscriber and a publisher. That explains why they're just sitting there waiting. I also passed a --help flag for some reason on the last one...bad copy pasting!

But in summary, I was able to run them again with the new code and it works! Thanks for the quick response :)
