Clutter in log files, bogus connections

I see a lot of clutter in log files from things like
  error:1408F10B:SSL routines:ssl3_get_record:wrong version number
I assume they are from bad guys probing for openings.

Is the error code returned by ERR_get_error() constant across releases?  Can I 
compile magic constants like 1408F10B into my code?  If not, is there a 
suggested approach?

Is there a list of well known attacks and their error codes?

These are my opinions.  I hate spam.
