If all of your GTMs are doing the health checking against the application, it could be that one or more of your GTMs can't reach it for whatever reason and mark it down. Then another GTM that can reach it marks it right back up, hence the bouncing.

 

Check /var/log/gtm and look at the reason the health monitor is failing. Take note to which units mark the pool member down, and which mark it up.
