[dtrace-discuss] Identifying anonymous errors, disabling anonymous tracing

When I booted with anonymous enablings, I saw

  ...
  NOTICE: enabling probe 8 (syscall:::return)
  NOTICE: enabling probe 9 (syscall:::return)
  ...

Then when I claimed the data, dtrace said

  dtrace: error on enabled probe ID 607 (ID 148: syscall::lwp_park:return):
invalid address (0xfe67a000) in action #1
  dtrace: error on enabled probe ID 607 (ID 148: syscall::lwp_park:return):
invalid address (0xfce7a000) in action #1
  ...

How can I tell which probe enabling generated the errors?  If ''enabled
probe ID'' is unique to each enabling, would it be unreasonable for the
NOTICE messages to print them?

Secondly, when I claimed the data, were the probes disabled?
