[CP2K:4281] A memory leak?

Do you have another mpi version to test? I've seen memory leaks with some
intel mpi versions.

HI, all

    I met a problem when running CP2K MD (version12507,  Intel
composer_x3_2013.1.117 + intel MPI + intel MKL + intel FFT on E5
intel CPU).

    When the jobs are running, the free memory of the nodes will reduce
quickly! Then cp2k calculations will exit with segment fault.
    To avoid the abuse of the restart files memory usage,   SAVE_MEM  is
set as .TRUE.. But it still doesnt work, the memory of the nodes reduced
quickly as well.

    Any idea about the problem? Is this a memory leak, maybe from the intel
compile and libs?
    Thanks a lot.
