We would need a model. If is not public you can sent it via email to OpenModelica@ida.liu.se and we will use it for debugging and then delete it.
You could also try the bootstrapped compiler as it has a different garbage collector which might perform better.

I will close this wontfix unless there are more details. Of course it is possible to exhaust memory for very complex models. In most cases it is easily solved by adding more RAM to the machine. It is also possible you found a bug for some combination of language structure, but we would need the complete model in that case.
