dlr update - wrong status

I tried to modify the dlr_mysql_remove to make it the same as 
dlr_mysql_update, simply by editing the dlr_mysql.c and making the 
dlr_remove to become dlr_mysql_update.

This would make the dlr's not be deleted when getting the last 
status-report and always updated to the "latest" dlr status, but 
instead, the status always gets updated to the value 135184161.

In the access.log, it does show as "Buffered" to "Success", but not in 
the sql update. Below i include log snippets.

Is this normal behaviour, or a wrong path i took along the way?
