UWL Wrong functioning after upgrade to 7.3

Hi,

We've upgraded Portal from 7.01 to 7.30 SP09 and UWL stop functioning:

1. Clicking over a worktiem and then clicking over another it shows the error “400   Session Not Found”.
   
   
   
2. Managing substitutions rules the user picker shows the message “No name found for: XXXX”.
   
   

Reading the system’s logs we’ve found the exceptions:

• Cannot clear ICM server cache by [718ac393010411e3a1fa000000d23c1e] etagIP address
• Failed to invalidate cached entry for user 718ac393010411e3a1fa000000d23c1e Exception:java.rmi.RemoteException: Cannot clear ICM server cache by [718ac393010411e3a1fa000000d23c1e] etag.; nested exception is: com.sap.bc.proj.jstartup.icmadm.IcmAdmException: interface disabled

Searching SCN post and OSS notes we’ve read and apply SAP Note 1635058 - J2EE crash in IcmAdm.getInstance, but the error persists. We also upgrade the UWL COLL PROCESS ENGINE 7.30 to the latest PATCH and still doesn´t working.

The system alias configured on the WebFlowConnector tests OK, already re-register the connector, clear the cache and restart UWL service.

Regards,

Gregory.
