I think this is more to do with ubic as it status is unkown or not running it never changed to working directory that was provided in config options
earlier using use Ubic::Service::Starman; i was getting ubic status as not runing.. and @INC
But now i changed it to below and ubic status is unknown.

use Ubic::Service::Plack;
my $Config={
       server => "Plack::Handler::Starman",
       server_args => {
            'listen'      =>'10.1.1.5:8080',
        'workers'      =>16,
        'backlog'      =>1024,
        'max-requests'=>1000,
        'daemonize'      =>'',    
        'reload'      =>'',    
        'user'      =>'perl',
            'access-log'  =>'/var/log/psgi/access.log',
            'error-log'   =>'/var/log/psgi/error.log',
            'app'         =>'/var/www/myapp/myapp.psgi',
        },
        app    => '/var/www/myapp/myapp.psgi',
        status    => sub {},
        ubic_log=> '/var/log/psgi/ubic.log',
        stdout    => '/var/log/psgi/stdout.log',
        stderr    => '/var/log/psgi/stderr.log',
        user    =>'perl',
    group    =>'perl',
    cwd    =>'/var/www/myapp/',
    pidfile    =>'/var/log/psgi/domfares.pid',
    };
return Ubic::Service::Plack->new($Config);

starman service is running though ubic status is unknown
Now ubic watchdog tries to start this service every minutes thinking it dead and service restarts every minute.

Why ubic status is unknown?
