Estimados: Poseo una bd postgresql en un entorno virtualizado bajo vmware y revisando los logs me encontre con lo siguiente:

Seguire investigando, pero si alguien sabe que puede estar pasando, talvez pueda echarme la punta del ovillo. Por lo que puedo deducir, podra tratarse algo respecto a la virtualizacion ? por esta linea: Pid: 22979, comm: postgres Tainted: G Gracias.
