Hello everybody,
We ran delta application with trawler for a few hours and we received
the following exception from the GUI several times:
Exception in thread "AWT-EventQueue-0"

Since everything seemed to be functional we ignored the problem and left
the network running for sometime more. Yet after a few hours we faced
the following exception and the graph disappeared though the network was
functional:
Exception in thread "Thread-4" java.lang.OutOfMemoryError: Java heap space
has anybody have the same problem with the trawler's gui? We have no
clue about what's going on. We do appreciate any help.
P.S. We are using delta application on tmote sky WITHOUT having low
power option.
thanks.
