SP13 - Problem with JCA connection

Hi,

We have a applied portal patch 13 some days back.

Since then all my connections to SAP using JCA is failing.

Before applying patch 13 these connections were working fine.

The connection test from the system is working fine.

System versions

J2EE - 6.40 PatchLevel 95420.313

Portal - 6.0.13.0.0

KMC - 6.0.13.1.0 (NW04 SPS13 Patch 1)

Following is the error message from server.log

Does anybody has an idea on this

#1.5#0003BAC255E5004000000071000052B10003FE9B1B59B7C8#1124367062382#/System/Server#sap.com/irj#com.sap.portal.connectors.R3#NAM60#1985####2501bca00fe111da81d80003bac255e5#SAPEngine_Application_Thread[impl:3]_21##0#0#Warning#1#com.sap.portal.connectors.R3#Plain###Failed in creating the JCO Connection. #
