Thanks hippo,

I've tried to malloc in smaller blocks. It's work better, but I see that if the malloc failed, after some tries the kernel kill my application.

How do I have to set the overcommit_memory and overcommit_ratio in

Which other kernel parameter have I to set, so that my system works properly, and to avoid that my applications are killed from the OOM_KILLER?

Can somebody help me?

thanks
