error => NiPconnect :Siconnect

Hi guys,

In my SMICM i had this trace :

[Thr 9] *** ERROR => NiPConnect: SiConnect failed for hdl 8 / sock 33

(SI_ECONN_REFUSE/239; I4; ST; 172.30.32.27:1) [nixxi.cpp 2518]

[Thr 9] NiICloseHandle: closing initial hdl 8

[Thr 9] *** WARNING => Connection request from (15/32/1) to host: aldesitg, service: 01 failed (NIECONN_REFUSED)

RM-T15, U32, 001 SOLMGR, INFOR-FON-MG09, 14:04:31, M1, W1, /TMW, 3/2 [icxxconn_mt.c 2321]

i've check my ICM is running, parameters fixed and service http maintain.

Any idea for this kind of error NiPConnect : SiConnect ?
