LEI Error: Invalid document handle or ID

When I excute LEI for replicaion between 2 notes DB, the Error: Invalid document handle or ID occured.

Detail log:

2011/06/30 02:33:17 Activity started

2011/06/30 02:33:24 Error: Invalid document handle or ID, Connector ‘WA46_wa46eols_KEIYAKU_Notes_Connection_Replica’, Method -Fetch- (0x80000E01)

2011/06/30 02:33:24 Current record key values at the time of the replication error –

2011/06/30 02:33:24 - Connector A record key values: ICNT = “C00319F0100”; DEXC8 = “20081101”

2011/06/30 02:33:24 - Connector B record key values: ICNT = “C00169F0400”; DEXC8 = “20080301”

2011/06/30 02:33:25 Activity Ended With An Error

As I have done test in other DB, the LEI activity seems ok. Maybe that’s the matter of document itself.

My question is : 1. what caused this error? 2. how to correct it?
