Ubuntu VPS quickly running out of ram
Hello everyone, Im new here and new to linux in general.
So I want to create this bitcoin service and decide to get a VPS. I installed Ubuntu because it seemed to be the easiest version to work with. But then today, as I connect to the server, I cant run anything without some error related to memory. I restarted the server and very quickly the same thing happened again. The bitcoin program takes up more than a GB, but that should be ok, given I have 4GB installed.
This time I restarted the server without running bitcoin and just click around in the GUI, looking at disk and memory usage with different tools. I close them all again and now we are at about 1.5GB of rams already used... I wait for a while and it is slowly climbing up (memory leak?). I then start bitcoin and run the comands posted below. What really gets me is that the sum of the memory percentages should never even reach 50%.
So what is going on? I am considering formatting and creating a swap space (thats for memory overflow, right?) and also go "headless" to save memory and to get rid of all the programs I installed, tried and forgot. But obviously I would like to know that the same problem wont just turn up again. Would any other distro be better suited for my purpose btw?
