[mpich-discuss] Help for strange MPI error

[Xiao Li]

Hi MPICH2 people,

May I know what does these error log mean? These error log occurr at the end
of my main function, just before the last statement "return 0". By the way,
I am sure the example program cpi.exe works fine on my small cluster.

[03:5672]......ERROR:result command received but the wait_list is empty.
[03:5672]....ERROR:unable to handle the command: "cmd=result src=0 dest=3
tag=35 cmd_tag=22 ctx_key=2 result=SUCCESS "
[03:5048]......ERROR:result command received but the wait_list is empty.
[03:5048]....ERROR:unable to handle the command: "cmd=result src=0 dest=3
tag=41 cmd_tag=22 ctx_key=1 result=SUCCESS "
[03:5048]...ERROR:sock_op_close returned while unknown context is in state:
SMPD_IDLE
[03:5672]...ERROR:sock_op_close returned while unknown context is in state:
SMPD_IDLE

cheers
Xiao
