If you want to know where the problem occurs, you can always copy

Suppose TeX complains about an overfull \hbox in line 7.

Line 7 contains the macro \foo.

Replace \foo by the content of \foo.  Then error messages will be more

I don't think that it is a good idea to turn off the messages.  It's
much better to find out what caused them.

If you are using LaTeX, try the draft option (\documentclass[draft]...).
It will put a black rectangle at the end of each overfull \hbox.
In plain TeX \overfullrule=5pt is the default.

You make TeX very happy if you set \hfuzz=\maxdimen \tolerance=10000
\hbadness=10000 because you allow it to do what it wants.  Otherwise
it has to provide good output which is very hard work, especially if
the values of the parameters you mentioned are quite small.

If you don't find a solution, please send us a minimal file which
describes this problem.  What we need is a small source file which
contains one macro which causes an overfull \hbox and the definition
of this macro.

Regards,
Reinhard
