2252269 - GW: RFC destination (Type T) fails when starting an external program

An RFC destination (Connection Type T: TCP/IP Connection) fails when starting an external program; RETURN CODE: 667.

There can be different scenarios:

 #Scenario 1:

Same information can be found on the work process trace file (dev_w<x>):

 M  ***LOG R49=> ThCPICSyncWait, CPIC-Error (001667) [thxxcpic.c   3450]
 M  ***LOG R64=> ThCPICSyncWait, CPIC-Error ( CMINIT(SAP)) [thxxcpic.c   3463]
 A  RFC 1234  CONVID CONVID 12345678
 A   * CMRC=1 DATA=0 STATUS=0 SAPRC=667 ThSAPOCMINIT
 A  RFC> ABAP Programm: xxxxxxxx (Transaction: SM59)
 A  RFC> User: <user name> (Client: <cln>))
 A  RFC> Destination: <RFC_Name> (handle: x…, DtConId:
 A  *** ERROR => RFC ======> CPIC-CALL: 'ThSAPOCMINIT' : cmRc=1 thRc=667
 Program (exec) could not be started

 A  *** ERROR => RFC Error RFCIO_ERROR_SYSERROR in abrfcpic.c : 1732
 CPIC-CALL: 'ThSAPOCMINIT' : cmRc=1 thRc=667
 Program (exec) could not be started
 DEST =<RFC_Name>
 HOST =<target_hostname>
 PROG =<Program ID>

SM59 error can also be:

In this case, work process trace file (dev_w<x>) will show:

 M  ***LOG R49=> ThCPICSyncWait, CPIC-Error (001667) [thxxcpic.c   3424]
 M  ***LOG R64=> ThCPICSyncWait, CPIC-Error ( CMINIT(SAP)) [thxxcpic.c   3437]

SystemLog entry (transaction SM21) that can be seen:
    12:34:56 DIA <nr>                                         R4  9 Communication error, CPIC return code 001, SAP return code 667

   #Scenario 2:

The failing program can be different from rsh:
   Error when opening an RFC connection (CPIC-CALL: 'ThSAPOCMINIT' : cmRc=26 thRc=667)
   ERROR: Start of TP ‘path\<program>.exe’ failed
   LOCATION: SAP-Gateway on <hostname>/ sapgw<nr>
   CALL: GwStartProgram
   COMPONENT: SAP-Gateway
   RETURN CODE: 667

The reported error on the work process trace file (dev_w<x>):
 M  **************************************************************************

 M  *  ERROR       Start of TP E path\<program>.exe failed

Same information can be found on the RFC trace file (dev_rfc<x>):
 Error RFCIO_ERROR_SYSERROR in abrfcpic.c : 1732

 Partner program fork failed

SystemLog entry (transaction SM21) that can be seen:
    12:34:56 RD                                         S3  3 fork failed, error 002

#Scenario 3:

The server runs in NT platform.

In the RFC Gateway (dev_rd) appears the error message:

M  *  LOCATION    SAP-Gateway on host <server name> / sapgw<instance number>
M  *  ERROR       Start of TP D:\usr\sap\<system name>\<instance name>\exe\<external program name>.EXE failed

With level 2 trace we see:

M  ThCPICRcSet: rqtype/cpic_rc/sap_rc = CMINIT(SAP)/CM_RESOURCE_FAILURE_NO_RETRY/FORK_FAILED
