What is the matter?

Here is another problem:
p2_10638: p4_error: net_recv read: probable EOF on socket: 1
p3_10649: p4_error: net_recv read: probable EOF on socket: 1
bm_list_10623: (223.890625) wakeup_slave: unable to interrupt slave 0 pid 10622
bm_list_10623: (223.890625) wakeup_slave: unable to interrupt slave 0 pid 10622
rm_l_1_10634: (223.757812) net_send: could not write to fd=6, errno = 9
rm_l_1_10634: p4_error: net_send write: -1
p4_error: latest msg from perror: Bad file descriptor
What is wrong?

1) please check your KPOINTS file., the symmetry analysis routines of vasp obviously have found different space group symmetries for your unit cell and the symmetrized k-mesh. It may help to generate an odd k-mesh, vasp can symmetrize odd meshes more easily.
2) these errors are not vasp related. please ask your sysyem manager if there are problems with your local MPI.

Thanks.
I used an odd k point, and resubmit vasp, however, the cpu time goes very slow, i.e it shows one minute, in fact 5 minutes have passed.
Is there some helpful tricks to guide vasp newers to select k points?

1) please read the k-points.pdf vasp-workshop tutorial handout (http://cms.mpi.univie.ac.at/vasp-workshop) to learn more about how to choose k-points efficiently. Usually, odd Monkhurst-Pack meshes are the safest choice.
2) there may be some large discrepancy between cpu-time and wallclock time, depending on how many (other) processes are running on the computer and how much swapping has to be done. If you run vasp parallel, please also check the processor communication.
