So I see in "task memory" was is going on inside the rpd and with
"sysem proc sum" I see the system over all ?

Im wondering, where I waste memory, cause there are many posts which state
that 512MB would be fine for 4 full tables. Ive only three and the 768MB are
full. 

Are there are some knobs to reduce the memory consumption like not to use
"softreconfiguration" at cisco boxes ?
