     -- We now ensure buffer policy is restored after RAS is done with a channel.
        This could cause audio problems on the channel after zapras is done
        with it. 
+ -- logger
+    -- The Asterisk logger will automatically detect when a log file needs to
+       be rotated.  However, this feature could put Asterisk in a nasty loop
+       that would result in a crash.
  -- general
