Please let me know , if any body had the similar error and find out the solution.
Environment : EP7.0 SP9, XSS 600 SP5
com.sap.mw.jco.JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE: System received an expired SSO ticket
Little description about the error on sdn is :
The SSO ticket has indeed expired .The default expiry time is 8 hrs. If you leave a system for more than this time, the ticket will expire. In that case you might need to increase the timeout value of the ticket.
There was also a bug on this in the earlier releases of Web Dynpro. The reasoning being that the tickets are held cached. The "expired SSO ticket" can also be caused by a JCO connection pool not having been destroyed when a WD application terminates. Then the same user starts another WD application using the same user id/authentication method/backend system combination. This is really a bug in that the Portal does not correctly notify the WD Framework that the WD app has closed. Hence the older ticket is still held and returned showing an Expired ticket error. The fix was in the UME so that appropriate notifications are sent to Web Dynpro regarding termination of the session. This is resolved from NW04 SP15 onwards. There was no reported issue on <b>NW04s</b>.
But as i said we are running on NW04s , still have the same issue.
