Estou executando minha máquina a partir da memória, e depois de sobrecarregá-la, ela ficará sem resposta até que uma quantidade significativa de memória seja liberada.
Minha máquina tem 16GB, minha imagem é de cerca de 3,5GB, e eu corri intellij, maven, etc. Eu ainda não consigo imaginar que estou chegando a 12GB ou mais, e muito menos 16GB. Se estou chegando perto dessa situação, prefiro receber um erro dizendo que não é possível alocar memória em vez de deixar de responder.
Minhas configurações de memória:
vm.oom_dump_tasks = 1
vm.oom_kill_allocating_task = 0
vm.overcommit_kbytes = 0
vm.overcommit_memory = 2
vm.overcommit_ratio = 100
vm.swappiness = 60
Os únicos erros que estou recebendo ao simular esse problema são:
