I am getting following error while testing JCO Connection.

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed Connect_PM TYPE=B MSHOST=sapserver GROUP=SPACE R3NAME=IDS MSSERV=sapmsIDS PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR max no of 100 conversations exceeded TIME Sat Jan 19 20:42:40 2008 RELEASE 700 COMPONENT CPIC (TCP/IP) with Unicode VERSION 3 RC 466 MODULE r3cpic.c LINE 10713 COUNTER 1

I increased profile parameters rdisp/max_comm_entries = 200 but it doesnot help so I change it back.

Any idea what is problem?

Thanks
