Internal Server Error

[Jordan McLain]

Hello,

I have a module that will fail every once in a while with the error_log
message:

Can't call method "send_http_header" on an undefined value at
/path/to/module/Name.pm

The handler method starts out with:

sub handler ($$) {
        my ($class, $r) = @_;

For some reason $r is not defined.  This only happens intermittently... Does
anyone have any ideas?
Apache/1.3.37 (Unix) mod_perl/1.29 mod_ssl/2.8.28 OpenSSL/0.9.7g

Thanks,
