1. is your backend, java standalone or dual stack ?

2. same error of HTTP 500, if bypass webdisp and connect directly to backend ?

3. any firewall / hardware load balancer sitting in front of webdisp ?

4. what did ICM trace said ? normally level 3 trace of webdisp and level 3 trace of ICM are required.

set parameter icm/trace_secured_data = 1 if using https

5. the error:

Thr 3204 *** ERROR => NiPConnect2: SiPeekPendConn failed for hdl 17 / sock 130760

(SI_ECONN_REFUSE/10061; I4; ST; xxx.xxx.xxx.xxx:8001) http://nixxi.cpp 2823

Thr 3204 *** ERROR => Connection request to host: PRD, service: 8001 failed (NIECONN_REFUSED) http://icxxpool.c 1968

- check the host PRD with port 8001...why is it refused....does it listening or used by someone else ?

6. what is the output of sapwebdisp pf=<profile> -checkconfig ?

webdisp version, kernel info, patch level ?

7. check SAP note:

Note 634262: Note on the preclarification of SAP Web dispatcher

Note 634006: ICM messages explanatory note
