UME error in Server0

Hi guys,

Our portal will no longer start up, getting UME errors in server0. Nothing should have changed that would have caused this problem. I have tried a number of different suggestions, including enabling the sap* user, turning off LDAP, and even redeploying the sap.core.ume component via SDM.

Wondering whether anyone else has had this problem before and can offer a solution.

Here is the error we are getting (same in both the std_server0.out and the defaultTrace files)

  Service configuration started. (102 ms).
