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

/proc/sys/vm ?

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

stepa
