I suggest

  "Do you want to auto delete previous execute log entries
   when record/replay buffer becomes full (record-stop-at-limit)?"

I'm not sure.  Can you explain what exactly does this message try to
say?  I will then suggest a better wording.

"Error executing process log record"?

"Error reading memory at addr = 0x%s, len = %d

By the way, is the address really a string (%s) here?

Yes, that's better.

I think you mean "make the execute log unusable from this point onward".

Yes, but I didn't mean to remove the question, only the "Process
record:" prefix.

The first line must be a complete sentence, because some help commands
(e.g., `apropos') show only the first line.

I suggest

    _("Delete the rest of execution log and start recording it anew.\n\")
