[gecode-users] Runtime problem

Hi,

I have implemented a scheduler with Gecodej 2.1.1 using Eclipse under WinXP.
The main scope can be summarized as:

for(int i=0, i<benchmarkNumber; i++){

    scheduler.loadBenchmark(i);
    scheduler.solveBenchmark(i);
    scheduler.printResult();
}

I am using a BranchAndBound strategy.
I noticed that for i=3 I get some suboptimal solutions but the B&B  
cannot be completed and the program exits with an error. I have  
attached the correspondent log file.
I tried with smaller problem instances and I noticed that the program  
exits around i = 5.
I suspect it is related with memory consumption.
Any help is very appreciated.
Thanks in advance!

Andrea
