This model died with \"Insufficient Memory/Stack Space Available!\", on a machine with 3GB of RAM and the shared memory settings 4x normal (OS X 10.5.6). BOINC 6.2.18 I believe. Another model died about the same time.

Any ideas why?

See my response here Edward.

I thought I\'d also posted that as a news item but I hadn\'t. Off to do it now.

Ah, thanks for that. I\'ve updated my preferences as suggested.

Here we go again... more failures.

This time a Mac which is happily running a 5.39 80 year model refuses to work with the 6.04 version. The machine is running OS X 10.5.6 and yes, I\'ve quadrupled the shared memory settings. BOINC 6.2.18.

I\'ve stopped the machine accepting new models until I know what\'s causing this. Again a Fortran compiler issue? While running 5.39, what models could this machine run? The current model has some time to go yet.

Well, the error message is that it doesn\'t have enough stack space, so perhaps you\'ll have to settle for one model at a time.

Thanks for the response. There\'s something I don\'t get there, because each process has a stack, be it Mac, Windows or Linux. Strange.

I forget the details, but I think that the hardware of Macs has a rather limited area for the stacks, compared to the other processors.

... but the hardware of Macs is the same as PCs, really, it\'s exactly the same CPU chip and chipset. This must be a software problem. I can understand the OS allocating less stack space that other operating systems, but each process is treated in isolation, there is no global stack space (not true for shared memory however), and one version of the model works, another doesn\'t. Perhaps I\'ll revert to BOINC 5.x once my current model is finished; I never had this problem with it.
