Slot-2 Total DRAM (KB): 262144
Slot-2 System (KB): 7488

Hi Svven,

you could use the command "top" and press to sort all the processes by memory utilization.

Sample output:

Mem: 390440K used, 593748K free, 0K shrd, 2908K buff, 156776K cached
CPU: 0.0% usr 2.6% sys 0.0% nic 97.1% idle 0.0% io 0.1% irq 0.0% sirq
Load average: 7.02 7.05 7.00 3/195 1909

1520 1 root S 4508 0.4 1 0.0 ./snmpSubagentProcess hal consumes 1.5% which can be used to calculate the approximate memory consumption of the process.

sh memory process hal

15236 is 1.5% of 1048576.
Hope this helps!
