`oom-top` is an additional diagnostic tool from the nohang package. It sorts the processes in descending order of their oom_score and also displays oom_score_adj, Pid, Name, VmRSS, VmSwap. It will be installed together with nohang. `oom-top` is an additional diagnostic tool from the nohang package.
