I have a CentOS 7 server that is running out of memory and I can't figure out why. Running "free -h" gives me this: ????????????? total??????? used??????? free????? shared? buff/cache?? available Mem:?????????? 3.4G??????? 2.4G??????? 123M??????? 5.9M??????? 928M??????? 626M Swap:????????? 1.9G??????? 294M??????? 1.6G The problem is that I can't find 2.4G of usage.? If I look

Hi, is this ok for a database server, or do I need to turn the memory allowance down? The machine has 48GB and mariadb is allowed about 40. The machine is a dedicated database server. Mysql seems to go up to what top says is virtually allocated under some circumstances; I don?t know what mariadb does. I don?t want anything get killed because memory runs out. Swap should prevent that anyway,

Disk cache is not recommended for databases servers. it'll slow down the performance. More ram equals more performance. This link help me understand memory usage on linux. https://www.linuxatemyram.com/ Basically you need yo worry about free memory is close to 0 used memory is close to total available memory (or "free + buffers/cache") has enough room (let's say, 20%+ of total) swap used does not change Warning signs of a genuine low memory situation that you may want to look...

Hello, We all know linux distros will use most of the free memory available for caching stuff, I/O buffers etc (hence sites like linuxatemyram.com). In many virt scenarios we have some sort of memory deduplication mechanisms, such as KSM on KVM (don't know how it's called in Vmware). My situation is one where I need to cram up as many virtual machines as I can on a single hypervisor and I believe KSM does not work for the memo...

They say that a healthy system should have at least 20% of the memory available.? Mine was down to 17% in what I posted in my email and...

We have DELL R900 server with 128GB RAM (CENTOS 5.5)in it. This server only have one application running and few people use it. Every week I ata least get one or two messages from monitor tool mail to me say: Message=Memory Utilization is 92.02%, crossed warning (80) or critical (90) threshold. Since server have 128 GB RAM and only 1 application. I really don't belive that. Does there
