Update: 
     Here's from the startup output and I can see its reading the suppression however the 137:1 's are still getting 
alerts.

I decided to try to suppress using:

Suppress gen_id 137, sig_id 1

But suppression doesn't seem to work, after restarting snort the alerts still get through. 

If I try at the snort.conf by commenting out the preprocessor wouldn't I be suppressing all SSL alerts? 

Thanks,

Hi All,
   If I want to limit or block all reporting on Snort Alert [137:1:0]

Would this work to limit it to one for every minute via the threshold.conf. Is there an easy way to block it all 
together?

event_filter \
  gen_id 137, sig_id 1, \
  type limit, track by_src, \
  count 1, seconds 60

yes, that will limit is to one alert every minute...

to disable it completely, you might comment the rule out in your 
preproc_rules/preprocessor.rules file if you are using that... i /think/ that's 
where the stub is located...
