[j-sim-users] null packets

[NooR]

Dear All.
   
  lately i faced the follwoing case: a set of nodes is receiving a null packetsfrom other nodes. i don't know how these packets are sents.
   
  i have a component called SinkComp at each node in top of the CSL, my defined port toCSL@ in SinkComp is connected  to csl/100 at up. 
   
  in SinkComp  i check for the packets that has body == null. and i found out that some nodes receives these packets that i don't send. 
   
  i tried to trace these packets using: setflag trace true n$i/SinkComp$i/toCSL@
   
  BUT the null packets disappears, when i turned trace to false the appeared again!!!!!
   
  any suggestions to overcome this?
   
  Regards
  NooR
