# A feature do pm2 chamada "vizion" tenta indexar o repositório do projeto de cada comando rodando. | |
# Em grandes repositórios e principalmente com um grande numero de processos rodando isso pode causar um | |
# grande consumo de memória e IO, o que impacta drasticamente a performance da maquina e dependendo da maquin, | |
# pode causar: "FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory" | |
# A seguir salvamos o estado do pm2 no arquivo ~/.pm2/dump.pm2, matamos o PM2 God Daemon e | |
# todos os processos que ele gerencia, alteramos o dumo.pm2 desativando a flag do "vizion" | |
# e ressucitamos o pm2 ao estado original. | |
