ER error

Im wondering if anyone has seen this error? 15:37:07 CDR CDRD_217: transaction aborted (One or more rows in atransaction defined with tx scope were rejected) with sql error 908 isam error 0. The 908 would indicate that the servers were not able to connect... but then why would I get the error on the receiving server? some data is still going back and forth but I am unable to completely sync up the data. When I do cdr list server (or cdr view servers) it shows all servers connected I did cdr stop and cdr start to try to 'jumpstart' things... and get this error on start 15:54:57 CDR GC: operation database syscdr exclusive failed (error -154). it tries 5 times... then doesnt say anything more I am trying to sync again now - after the cdr stop/start. My next course of action is to bounce the whole engine. But I dont really want to do that. Any help is appreciated. Laurie :)
