Lack of resource on CentOS 7

[cuongnn]

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.

Hello TrevorH

The total memory resource of all process in ps command is too small but in htop it show around 5 GB, therefore i want to know which process is take more resource.

Thanks

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.

Thanks TrevorH

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
