Memory problem

Dear all,
I'm performing a total of 540 simulations with ichthyop stable 3. Unfortunately the model crash down after 92/540 beacause of memory problem. I got the following error message:
ichthyop[severe] null | java.lang.OutOfMemoryError
Does anyone have an idea on how I can solve this issue?

Hydrodynamic dataset: 
ROMS
Operating system: 
Ubuntu

Hello,
If this is a heap space momory error, you should be able to avoid this problem with the command line:
java -Xms512m -Xmx1024m -jar ichthyop-3.2.jar.
You also could add more memory if your computer allows it -Xmx4052m.
Hope it solves your problem,
Lysel
