Caida de servicios
Anuncios Posted by Victor Martinez on Tuesday April 17, @04:13PM el 2007
from the !diantres con el oom killer! dept.
Bueno anoche linux, sufrio de algo similar al efecto /. y aun cuando linux no tiene configurado el oom killer, la maquina se quedo sin memoria.
Por lo cual empezo a matar procesos para seguir en pie, esto en la practica parece que fue un tanto peor, puesto que dejo fuera de linea el correo y con todo el apache se quedo atorado.

Voy a aprovechar para recompilar el kernel de linux y talleres. Aun no se si incluir el oom killer. A partir de las 8 pm tuvimos problemas

Voy a hacer tweaking en la configuracion de apache, para limitar la cantidad maxima que puede utilizar de memoria (aunque no deberiamos tener un evento asi de nuevo, por cierto en pesimo momento).

Tambien pensaba en poner otra maquina a monitorear linux, pero talleres y sagan usan linux como smarthost.

      Nos visitaron varios webspiders no bien portados, apache se acabo la memoria fisica y la del swap, el kernel, para mantener el sistema funcionando empezo a matar procesos.

      En algun momento un hijo de apache se quedo zombie y no lo pudo matar el VM del kernel, asi que el mismo se siguio matando otros procesos, para liberar memoria, los cuales salen enumerados, para cuando me di cuenta de que esto estaba pasando, fue por que me llamaron por telefono por que habia un evento en el que tenian que mostrar la galeria, como eran muchos servicios abajo, mande un init 6 en lugar de tratar de levantarlos uno por uno.

      Saludos.
