OutOfMemory exception ao elevar o número de requisições no Broker localmente #68

Closed pedrofgd closed 1 year ago

pedrofgd commented 1 year ago

Estamos tendo esse erro no Broker ao rodar com um pouco a mais de carga... esse erro veio ao executar o teste de carga demo.js com o k6, que envia 100 requisições ao longo de 5 minutos, aguardando no mínimo 2 segundos entre cada requisição, o que já é bem pouco.

O que está causando é o LoggerFactory, parece, que está criando uma nova instância várias vezes, na mesma requisição, e que cria novas a cada requisição recebida.

Já tinha um "To Do" #53 para ajustar essa questão no futuro, mas vai ter que ser corrigido agora, para poder executar os testes para colocar no artigo final.
