[Tinyos-help] sendDone getting lost

Hi 
   I found that under heavy traffic sometime I don't receive 
a sendDone after a SendMsg.send(). As I am using QueuedSend 
the code breaks as the queue eventually gets full. 

The only case when this can occur is if a high priority 
interrupt occurs exactly at the same time when the interrupt 
for sendDone is generated.

I observed this long ago with mica2 and now I observe the 
same on tmote. I was wondering if this has been solved or if 
there are smart work-arounds for it. 


Thanks,
Sumit
