I am using the EnsLib.RecordMap.Operation.BatchFileOperation to write a batch to a file but for some reason this has been working fine as of yesterday I had a problem with the cache databases filling up running out of memory so had to compact my database and gain space now when I run the operation I get the above error .Of course in my batch table there is no batch record with ID 1.The message is passed with the correct header information but still get this error any suggestions why?
