I am running a ps command on solaris to get SZ and RSS values, here is the sample output
USER-PID-%CPU-%MEM-SZ-RSS-TT-S-START-
root-3-0.1-0.0-0-0-?-S-Feb-
qacom2-7440-0.0-0.0-3912-3344-pts/7-O-13:25:22-
root-6589-0.0-0.15985621000-?-S-Feb-08-1309:34-
If you see this outpuit, for PID 6589, SZ is '?' and RSS is 'S' what exactly this indicates?
