Not a hacker myself, but I can tell you that the first question you'll 
be asked is "can you produce a test case"? If you can generate the 
problem from a test table+generated data that will let people figure out 
the problem for you.

If not, details of the table schema will be needed, and is there any 
pattern to the missed rows? Also - compile settings, character set and 
locale details might be relevant too.
