I am getting the following deadlock?  One of the locks does not have a user or SQL associated with it.  What should I be looking for when a lock is described in this way?

Lock : ROW, FILTERS_FOR_DELIVERY, (3,1960)
  Waiting XID : {271243, X} , VONTU, DELETE FROM FILTERS_FOR_DELIVERY WHERE ITEMSET_ID = ? AND FILTER_INDEX = ? AND SERVER_ID = ?
  Granted XID : {271250, X}
Lock : ROW, FILTERS_FOR_DELIVERY, (3,1990)
  Waiting XID : {271250, X} , VONTU, DELETE FROM FILTERS_FOR_DELIVERY WHERE ITEMSET_ID = ? AND FILTER_INDEX = ? AND SERVER_ID = ?
  Granted XID : {271243, X}
. The selected victim is XID : 271243.

Thanks,

David
