This is emitted by some code that registers userland DTrace probes during process init. The mechanism used in stable/10 doesn't work in some cases. This has been fixed in 11, but the change cannot easily be merged back. > > Any chance of getting rid of the messages, or at least disabling them? If you're not planning on using the DTrace probes, the message can be suppressed by setting DTRACE_DOF_INIT_DISABLE in the environment. > > This is on stable/10, r310494. > > /etc/make.conf contains: > > STRIP= > CFLAGS+=-fno-omit-frame-pointer > WITH_CTF=1 > WITH_SSP_PORTS=yes > > This particular system will soon be upgraded to stable/11, r310770. > Maybe my troubles will disappear once the transition is complete. Indeed, this message is gone on stable/11.
