I'm seeing the same on a Pi3 v1.3 running Fedora 40 IoT. I've put 6.8.7 on it to make it more similar to my other devices. It seems to fall over after about 11-12 hours. This device is mostly always idle until called upon to run the occaissional build test. I have two more Pi3 (one v1.2, one v1.3) running a more "standard" Fedora 40 with 6.8.7 which don't exhibit the problem. These two have something running continuously although they're not heavily loaded. I'm still trying to identify where the memory is going but kmalloc-4k in slabtop appears to be the difference (only managed a few hours of comparison). Still present on 6.8.7-200.fc39.aarch64. It lasted about 12 hours before running through the 8 GB of RAM. I also haven't figured out where it's going. It's not user space. First impressions are that this is fixed in 6.8.9 Yes, there was a fix for this that made it into 6.8.9 FEDORA-2024-3697e3b459 (kernel-6.8.9-200.fc39) has been submitted as an update to Fedora 39. https://bodhi.fedoraproject.org/updates/FEDORA-2024-3697e3b459 FEDORA-2024-c90afc5c01 (kernel-6.8.9-300.fc40) has been submitted as an update to Fedora 40. https://bodhi.fedoraproject.org/updates/FEDORA-2024-c90afc5c01 FEDORA-2024-3697e3b459 has been pushed to the Fedora 39 testing repository.
