Error 28 is #define ENOSPC 28 /* No space left on device */ This seems like a bug to me: when a filesystem fills you shouldn't be getting this behaviour. Can you please follow the directions in the developers handbook chapter on kernel debugging, and when you trigger a hang, break to DDB from the console and force a dump, then file a PR and make the core file available to the developers. Unfortunately unless a developer can replicate the behaviour, providing access to a core is the only real debugging option. Thanks, Kris
