DTrace not working

[sky67]

Hello,

I have latest stable FreeNAS 9.3 version and I am unable to run DTrace. Running it, for example command dtrace -n 'sysinfo:::writech { @bytes[execname] = sum(arg0); }', ends up with error "/usr/lib/dtrace/psinfo.d", line 89: failed to resolve type kernel`struct thread * for identifier curthread: Module is no longer loaded

Module dtraceall is of course loaded.

Why is that?

Thanks.
