Problems after updating to 4.2.1.7

Hello, We had Tamino running on version 4.2.1.5 on SuSe Linux. We updated to 4.2.1.7 and since then we have no access to the databases. The services seem to start OK but the hub says “there is no elements to display” when clicking on the host name. Are there any ideas how to fix this ? As a workaround we tried to backup the database on Windows Server 2003 (with the update installed). The backup (made still on version 4.2.1.5) itself ran successfully but when we tried to start the database it has given a ‘signal 11’ received and the startup failed. Can somebody help on this ? regards, Bal
