Replication apparently to be working, but just 2 of 4 DB are replicating

[Ramon Resendiz]

The replication is compossed by 1 Master (5.5.27) and 2 Slaves (5.5.27 and 5.1.50). One of the slave work perfectly (5.1.50), the 2nd one is working at half, i mean the schemas that are supposted to be replicating are 4, but just 2 of them are replicating.

I've did copy from master to slave, so many times, and set the replication a lot of times. But no matter what it do, i only can do that schemas db1 and db2 replicate in a correct way from master, but db3 and db4 do not do it.

BTW there is not any clue about why coudl this be happening.
