1891193 - SAP system cannot start due to local ICM is not connected

Symptom

SAP system is not starting . Disp+work process shows gray with stopped status in SAPMMC. Work process is died.

1. Below error can be found in dev_disp and dev_w* traces:

M  ***LOG Q0I=> NiPConnect2: 127.0.0.1:64998: connect (10061:
WSAECONNREFUSED: Connection refused) [nixxi.cpp 3286]
M  *** ERROR => NiPConnect2: SiPeekPendConn failed for hdl 1/sock 1396
    (SI_ECONN_REFUSE/10061; I4; ST; 127.0.0.1:64998) [nixxi.cpp    3286]
M  *** ERROR => IcmConnect: NiConnect to localhost:64998,-1 (rc=-10)
[icxxext.c    182]
M  *** ERROR => ThPlgConnectToIcm: IcmConnect failed (-10) [thxxplg.c
 5137]

Dev_icm trace shows :

IcmInit: listening to admin port: 64998

Work processes in local host cannot connect to ICM via ICM admin port 64998.

Here port 64998 can be any ports from 65000 downwards.

Error code of "10061:WSAECONNREFUSED: Connection refused" is from Windows platform and is platform-depended. 

2. There is another chance that below errors logged in dev_w* traces when local ICM is not connected and work process died after this error :

M  ***LOG Q0I=> NiPGetHostByName: hostname 'localhost' not found:
gethostbyname (11004: WSANO_DATA: Valid name, no data record of
requested type) [ninti.c 320]
M  *** ERROR => IcmConnect: NiConnect to localhost:65000,-1 (rc=-2)
[icxxext.c    179]
M  *** ERROR => ThPlgConnectToIcm: IcmConnect failed (-2) [thxxplg.c

In dev_disp trace, there is error like as below :

*** ERROR => DpWPCheck: W0 (pid 6780) died (severity=0, status=0) [dpxxdisp.c   15884]
*** ERROR => DpWPCheck: W2 (pid 6744) died (severity=0, status=0) [dpxxdisp.c   15884]
