Guessing that you are using modperl 2.0:
print in mod_perl 2.0 is really $r->print (and implemented via perltie on 
STDOUT). It returns the number of bytes buffered/sent, not the success or 
failure. If there is an error it'll croak, so there is no need to check 
the return value.
http://perl.apache.org/docs/2.0/api/Apache/RequestIO.html#C_print_

I didn't check mod_perl 1.0, but it's probably similar.

In the future when you ask questions here, please first read:
http://perl.apache.org/bugs/ and save us the guessing part. Thank you.
