SXPG_COMMAND_EXECUTE issue

Question

Hello Experts,
We have this issue in client server.One of the batch job is frequently failing while executing this function module SXPG_COMMAND_EXECUTE with error as command_not_found.This error occurs frequently on a particular application server but not all the times it fails but we find some job failures 2 to 3 times a day,as this batch job is running every 15min.Please find the sample code below and advice.Many thanks in advance.
  CALL FUNCTION 'SXPG_COMMAND_EXECUTE'
       EXPORTING
            commandname                   = 'ZZ_YP_MKDIR'
            additional_parameters         = w_command
       TABLES
            exec_protocol                 = i_command_results
       EXCEPTIONS
            no_permission                 = 1
            command_not_found             = 2
            parameters_too_long           = 3
            security_risk                 = 4
            wrong_check_call_interface    = 5
            program_start_error           = 6
            program_termination_error     = 7
            x_error                       = 8
            parameter_expected            = 9

            jobcount_generation_error     = 14
            OTHERS                        = 15.
  IF sy-subrc = 0.
    LOOP AT i_command_results.
      WRITE: / i_command_results-length,
               i_command_results-message.
      IF i_command_results-message <> space.

Hi swathv     
That function is used for calling Unix scripts on the application server,
You can specify a unix script as a command on transaction SM69
and than you can call this command with function 'SXPG_COMMAND_EXECUTE'
Can you find this command in SM69 and related script,
and learn what is it used for?
Maybe you are using more than 1 application server,
and script file exist on a server but doesn't exist on other.
I hope it helps.
