Servidor Apache comendo muita memória RAM

Assuntos Gerais
#1

Olá, tenho um servidor VPS linux.

vendo pelo “htop” ele fica com 27, 30MB de memória RAM usada…

quando eu do start no meu tomcat 7, ele vai pra 712MB

to achando isso muito estranho :’(

alguém tem ideia do que possa ser?

obs.: não tenho nenhum projeto feito deploy

#2

É preciso lembrar que o Tomcat é uma aplicação Java, sendo assim, vale a pena conferir no startup.sh quais valores são passados para os parâmetros -Xms e -Xmx para iniciar a JVM. Eles informam o tamanho inicial do heap e o tamanho máximo do heap. Pode ser que o tamanho inicial esteja sendo configurado para usar por volta de 700MB.

Olá rmendes08,

primeiramente obrigado por responder…

andei olhando meu startup.sh e não enconhei nada sobre o que você falou…

tenho uma cópia dele em txt neste link:

da uma olhada no startup.sh e catalina.sh.

ve se você encontra la algum “export -Xm”
