Thank you. On the Console Output  for the instance i-078f1e09aef72690a I can see that it has experienced an internal memory exhaustion due to which kernel started to kill various processes to free the memory up. As the instance is t3.micro with 1 GiB of memory, perhaps you should consider resizing it  to an instance of a larger size  that can support your applications' requirements better.
