tcp reassembly for multiple connections simultaneously help needed

hi all

i m trying to build and save (in separate files) tcp sessions for
multiple connections from sniffed data.
i have tried to save data after NIDS_CLOSE || NIDS_RESET option but it
does not work .. (i dont know why) .. it writes garbage in file . or
sometimes very small amount of data (perhaps buffer size has to b
increased but TCP->CLIENT.BUFSIZE does no good). ( i need
multithreaded like support). saving data at option NIDS_DATA is no
helpful as i need to save data for each connection in multiple files.
any suggestions regarding solution of the problem...

waiting for the reply ..

regards
alqama
