Estimados, antes que nada gracias por su tiempo.
Tengo el siguiente caso en un servidor de aplicación Jira de producción:
El servidor tiene 12 GB de RAM, se toma toda la ram y la guarda en cache como se puede ver a continuación:
# free -m total used free shared buffers
cached
Mem: 12011 11946 64 0 17 91 -/+ buffers/cache: 11837 173 Swap: 5951 7 5944
no, eso NO está bien, NO está guardando en caché. La memoria de caché es 91MB, es bajísima.. el resto es la memoria bloqueada por procesos (memoria no descartabla, no swapeable en su mayoría)... que es 11837, está muy mal la cosa

deberías ordenar por memoria apretando la M mayúscula.
Este es el proceso de la maquina virtual Java corriendo:

no sacaste completamente todo... ps auwwx|egrep java quizá saque más info
Pueden ayudarme a darme cuenta por que motivo se almacena tanta memoria
en
cache??
ps ax también tiene un switch para que puedas hacer sort por memoria, lo que te interesa es la memoria reservada (RSZ creo que es).
