Tenho um problema com o escravo Jenkins sendo encerrado durante a execução da compilação.
- SO: Windows 2012 R2 (Master e Slave)
- Java: 1.8.0_211 (Mater e Salve)
- Versão Jenkins: 2.176.2Slave
- Método de inicialização: Java Web start, JNLP (Iniciar conectando-o ao Master)
Problema: tenho um projeto no Jenkins que falha principalmente porque o escravo termina após 'Iniciar o ServiceWrapper no modo CLI' durante a execução. Encontra um processo filho conhost.exee falhou devido a Killing como substituto.
Isso está acontecendo apenas para um projeto/pipeline, onde tenho um script python que executa ping em uma URL interna (https://URL/ping), invoca a ferramenta de emulador de rede instalada, ajusta a latência da rede e também grava em um arquivo/push para ELK. Eu tenho um proxy de Internet configurado usando o arquivo .pac.
Ele completa todas as etapas do projeto, ao final o escravo finaliza, marcando a construção como falha.
Nota: Também temos outra versão antiga do Jenkins 2.76 instalada onde o mesmo projeto/pipeline funciona sem nenhum problema. Agora queremos atualizar para o Jenkins mais recente e estamos vendo problemas com o encerramento do escravo. Agora tenho que fechar a ferramenta do emulador de rede todas as vezes e reiniciar o serviço Jenkins para colocá-lo online novamente.
