Go app shutting down too often

[Delasoi Odupoi]

I have an issue with the Go app that has been deployed on App Engine. From 16/10/2019, we have been having an issue of it shutting down ever so often - sometimes with the error without having changed anything on our end. This means, that customers are locked out from processing their requests because they get 500 errors.

• Start program failed: terminated process with error signal: terminated
  
• Start program failed: terminated process with error exit status 1
  
• Container called exit(1)

Anyone know what might be triggering this?
