I'm  getting received these error messages

**************
Fatal error in PMPI_Comm_split: Other MPI error, error stack:
PMPI_Comm_split(557).................: MPI_Comm_split(comm=0xc4000004,
color=10, key=10, new_comm=0x7fffffffa788) failed
PMPI_Comm_split(533).................:
MPIR_Comm_split_impl(270)............:
MPIR_Get_contextid_sparse_group(1318): Too many communicators
(3141/16384 free on this process; ignore_id=0)
**************

I suspect it may be caused by the lack of

 mp_barrier()

call in my code, which is using calbec() routine to get overlap matrix
between KS orbitals at t-dt and t steps.

Could anyone comment on that?

Thanks in advance,
Ilya
