Eu uso um ambiente de computação de 0-256 m3.medium sob demanda. Minha definição de trabalho requer 1 CPU e 3 GB de RAM, que o m3.medium possui.

Quais são as possíveis razões pelas quais as Tarefas em lote da AWS estão presas no estadoRUNNABLE?

AWS diz:

A job that resides in the queue, has no outstanding dependencies, and is therefore ready to be scheduled to a host. Jobs in this state are started as soon as sufficient resources are available in one of the compute environments that are mapped to the job’s queue. However, jobs can remain in this state indefinitely when sufficient resources are unavailable.

mas isso não responde minha pergunta
