amazon ec2 - EC2 micro instance memory issue -

I'm running a micro install in EC2 with 592 MB available RAM

Jenkins is out Was crashing due to the memory build errors while running an update on the large SQL table in the backend.

Disc usage is done from 83% to 8 GB EBS volume with 6 GB.

  sudo du - hsx * | Sort-rh | Head-10 / 2.7G Opt 1.5G V 1.2 G USR   
 I got at least 6 MB free - "Free M" is running with these services -  
   
 Then, I had closed Jenkins  
 , it was created 320 MB free space, by eliminating MySQL 5.6 It is delivered to 399 MB free space.  
 Then, 200MB of RAM is still running in any of my services  
  what is on Amazon EC2 Running Ubuntu micro insta The minimum requirement of 200 MB of RAM for the session? No, I believe it can run up to 100% of the usage.    
 
 
  
 If there is any work that is available Large memory is required, the task is killed  
 To free more memory space, you can run it from your terminal  
  sudo apt- Get autoremove
