error occured when running case

[tckm@whu_edu_cn]

Hi,
Excuse me for asking help. I met a problem when running case with f19_f19_mg16 res、FXSD compset on my own ported mahcine. The case always aborted when running after some times. The cesm.log shows :

GHP7 NOT CONVERGING FOR PRESS 3.55E-10 NaN
GHP7 NOT CONVERGING FOR PRESS 3.55E-10 -1.78E-02
GHP7 NOT CONVERGING FOR PRESS 3.55E-10 -1.93E-01
GHP7 NOT CONVERGING FOR PRESS 3.55E-10 NaN
GHP7 NOT CONVERGING FOR PRESS 3.55E-10 -1.96E-03
BalanceCheck: soil balance error nstep = 3177 point = 12505 imbalance = -0.000000 W/m2

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Backtrace for this error:
--------------------------------------------------------------------------
A process has executed an operation involving a call to the
"fork()" system call to create a child process. Open MPI is currently
operating in a condition that could result in memory corruption or
other system errors; your job may hang, crash, or produce silent
data corruption. The use of fork() (or system() or other calls that
create child processes) is strongly discouraged.

The process that invoked fork was:

Local host: [[60281,1],151] (PID 10182)

If you are *absolutely sure* that your application will successfully
and correctly survive a call to fork(), you may disable this warning
by setting the mpi_warn_on_fork MCA parameter to 0.

mpirun noticed that process rank 151 with PID 10182 on node n0236 exited on signal 11 (Segmentation fault).

Then i turn the dubug on ,and receive the new cesm.log attached.
Anybody knows how to solve this problem. Thanks for helping me.
