After a lot of “doh” I realised that it was a dtrace script which was matching a lot of probes running as part of some automated stuff. The problematic part from the middle of that script was a section which I can reduce to fbt:kernel::entry # or simply ::: /self->foo == 1/ { printf(“Hello\n”); } Anyone wants to investigate this or should I open a PR? /bz
