Matlab crash; Java HotSpot(TM) 64-Bit Server VM warning

Hi,

I run some simulations in Matlab and sometimes the Matlab crashes and creates some files java.log.(some number). These files contain the following message on a few lines:

Java HotSpot™ 64-Bit Server VM warning: Attempt to allocate stack guard pages failed.

Does anyone know what is the cause of this? This happens at random times, so the same matlab simulation sometimes finishes without any problem, and sometimes crashes. In the command window it shows something like this:

??? Error using ==> sbioloadproject>createMATFile at 182 Error opening project file "/net/nikkafs/fs2/rchereji/Matlab/Projects/Simbiology_Reduced_Param/Rescaled/WT/Wild_Type_Reduced_V2_V10_V12_t2.sbproj".

Any help would be appreciated.

Answer 1

Per Walter's suggestion, you can try increasing the Java heap via a MATLAB preference.

If that doesn't help the problem, you may want to contact Technical Support.

Answer 2

Increasing the java stack size might help, maybe.

And how can I do that?
