Comment # 25 on bug 1114589 from Aleksey Kontsevich

(In reply to Aleksey Kontsevich from comment #24)
> Set -s 100 and added -p switch.

   -s PERCENT[,KILL_PERCENT]
       set free swap minimum to PERCENT of total (default 10 %).  Send SIGKILL
if at or below KILL_PERCENT (default PERCENT/2), otherwise SIGTERM.

       You can use -s 100 to have earlyoom effectively ignore swap usage:
Processes are killed once available memory drops below the configured minimum,
no  matter much swap is free.

 -p
       Increase earlyoom���s priority: set niceness of earlyoom to -20 and
oom_score_adj to -1000
