[ns] missing drop target / reducing memory consumption

[Neundorf Alexander <Alexander.Neundorf.extern@icn.siemens.de>]

Hi,

I'm doing wireless simulatiuons and want to reduce memory usage. One node causes in my case a memory consumption of approx. 140 kbyte due to 8 CMUTrace objects per node. 
How can I get rid of them ?
I commented ns_ trace-all $fd out, and now I get 

no object
   (_o36 cmd line 1)
  invoked from withtin
"_o36 cmd dropt_target {}"
   invoked from withtin
"catch "$self cmd $args" ret"
   (procedure "_o36" line 2)
   (SplitObject unknown line 2)
   invoked from within
"$arptable_ drop-target $drpT"
   (procedure "_o21" line 43)
   (Node/MobileNode add-interface line 43)
   invoked from within
"$node add-interface ....."

Any ideas what went wrong ?
I think I didn't mess this stuff up.

Bye
Alex
