Lack of resource on CentOS 7

Post by cuongnn » 2019/05/14 04:38:03

Dear all,

I have problem with the resource on CentOS 7 when i show with htop and free command. My server are running Tomcat 8.5.39 ( hosting java website) and Postgresql-11, I have already stop these services but the memory used is still high and I cannot find what process is taking it . Could you suggest me the solution to check this case ?

I also attach the screenshot and the list of process by ps command.
Thanks so much.

You haven't shown us any evidence of anything wrong.
CentOS 5 died in March 2017 - migrate NOW!
CentOS 6 goes EOL sooner rather than later, get upgrading!

Maybe this is just a case of "Linux ate my RAM!" ?

How about you show us the output from `top` - you did say you had a screenshot but it's missing.

I attach the screenshot again, but i think in my case it doesn't related to disk caching because i see that the system also use the swap file :roll:
