I have a replication for which the commands are moving fine from distributor to subscriber but when i insert a tracer token, one out of the 5 subscribers isn't getting the token.... the tracer token tab in replication monitor shows pending for distributor to subscriber latency for this subscription... although any changes made in the articles is replicating just fine...

Anyone has any idea as what the problem could be... this is happening for a 2005 -> 2005 replication and also to a 2008 -> 2008 one... the subscriber and publisher database involved in these two replications are also used in several other replications but i don't see a problem there..
