Lines of code related to this message :

                #not defined, the normal case
        if (! defined $self->{warp_message} ){
                #join any message elements
            $p->{message} = 
                join($Log::Log4perl::JOIN_MSG_ARRAY_CHAR, 
                 @{$p->{message}}  <== line mentioned in message 164 
                     ) if ref $p->{message} eq "ARRAY";

Now the problem is after successful push the pushed files are not coming in the server repo. I don't know what I am doing wrong. Am I doing push in a wrong way or the problem is due to the code.
