I am running 4 nested domains with WRF v4.5.2. After around 12 days' run, WRF was killed showing the following memory error (see the attached namelist and error log). I search the old posts and find it could be caused by using two many CPUs. I reduced my CPU usage from 160 to 120 and changed time step from 72 to 36s, but did not solve the issue. Any suggestion on how to do the next? Thanks!
