Deadlock in SQL replication

I have a transactional PULL replication on SQL 2008,I hv created individual publisher and subscriber for every article.

In my replication monitor my most of the subscribers are showing status

        'Retrying Failed Command'

and details r given that

'transaction was deadlocked on lock resources with another process and has been chosen as the deadlock victim ' 

when I chk d errorlog it gives me table "MSreplication_subscriptions" where all deadlocks are occurring while updating.

Even I rebuilt the indexes on that table but no effect.

Kindly suggest on the same.
