Out of memory

I am runing a simulink model via ascript file named as Run_TCMA_Performance on the following plat form

MATLAB Version 7.11.0.584 (R2010b)
Operating System: Microsoft Windows 7 Version 6.1 (Build 7601: Service Pack 1)

and receving following error:

??? Error using ==> Run_TCMA_Performance at 62
Error due to multiple causes.

Caused by:
    Error using ==> Run_TCMA_Performance at 62
    Data logging exceeded available memory
    Error using ==> Run_TCMA_Performance at 62
    Cannot allocate sufficient memory for log variable ''. Consider
    disabling logging or reducing the length of the simulation

    Error using ==> Run_TCMA_Performance at 62

I can understand that my machine is going out of memory. However, data is in the work space and I can manually save it. My question is why I cant save it automatically?

Thanks

Just to clarify, I have deleted most of the variable which I was saving even then the problem persists.

James, Thanks for the reply. However, I solved it by removing scopes. There were two scopes which were storing data at 1e-6 sample time. They were hidden inside the model so did not remember them and these were creating memory problem. Removal of these scopes worked for me.

Thanks Khalid

I had a similar problem which occurred at the same time in each run despite there being plenty of available RAM (according to Task Manager).

I solved the problem by manually removing a discontinuity from the data stored in a .mat file I was using as an input. Whilst this may not seem related to running out of memory, it fixed the problem
