EC2 instance shows status check fail during couple out instances.

Question

Hi,   
  
I have status check failures couple of times this week.   
id: i-b1c7d047  
  
Initial troubleshoots:   
 - Checked the perfomance metrics of the instance, not more than 50 %.   
 - ELB access logs shows 504.  
Digging more on the logs  
  
Meanwhile,  
I was wondering if there might be a reason, why I receive these failures?   
Is it common of this failure occurrence. Do other's have similar experiences?   
  
Thank you,

Hi there ,  
It had happened due to system status check failure.  
I would ask you to make use of Autoscaling group behind ELB so that these events can be handled automatically

as in post https://forums.aws.amazon.com/thread.jspa?messageID=886201&#886201:  
We have the same situation , and looking at the situation during the 504 errors they happens when the Target group contains one or more instances in draining state.  
I think ALB needs some time to understand that an instance is not available. But this is not the right behaviour
