I have a process that will load a couple of million records in BO to do a duplicate record search. My process will import thousands (360K+) of records and then I need to make sure those records does not exist in the database, so instead of querying the data 360k+, I load a BO with all possible duplicate records to check against and this is the million records BO.



Now the problem is that even when I do a BO.Clear to remove those records the application keeps using a lot of memory (over 1gb) and that memory is not released until the whole application is closed, so when the import process starts again, it will blow up with a not enough memory to complete the process.



So what should I do in order to make sure that the memory used once the million record BO is filled is released when using BO.Clear?



Also I am open to suggestions to change my approach if I need to.



Thanks!
