I am trying to figure out what is using all the memory on my system, can anyone help? My dedicated server has 16gb of ram, and I am currently running a minecraft server @ 4gb, an apache web server, and a teamspeak server. It shouldn't be using that much, but I think it is using up to 90% of my resources. Here is what I found using top and free:
4Gb for minecraft...... 12GB for Apache and Teamspeak....... Apache uses virtually no resources....... Teamspeak uses virtually no resources....... That is your problem....... And I would suggest using htop instead. Much easier to read.
Supposedly its just "virtual memory" and my applications are not actually filling all of the ram... is this assumption a possible answer?
No, its not using 90% .. you are reading free output wrong. look for the free value after including cache and buffers: 10176MB .. so you have lots of ram that can be used.
