Hi Thanks for everyone's input. I came across and liked the smem prog for showing "fair share" mem usage and am using it in a script that looks at RAM+SWAP limit (that I decided on) and it kills whoever is using the most at the time. In the future I hope to succeed in configuring cgroups to enforce fair sharing of memory. Does anyone know of a good cgroups forum? I also wrote a script to monitor cpu, mem and users every 5 min and accordingly came to the decision to ask for more memory. Thx, Josh
