change the memory size setting in netlogo batch file may solve this issue. as the default low of maximum memory is low, this issue usually happens when you hae a simulation with large quantity of agents.

change it to 1024M is what i did before. try to make your own script and submit it with local modified netlogo batch instead using the standard version provided by hpc.
