Replication Complaining on slave with every new binary log from master. (no replies)

I have replication configured and I have noticed in the mysqld log file on the slave the following errors:

101208 11:00:49 [Note] Slave: received end packet from server, apparent master shutdown:
101208 11:00:49 [Note] Slave I/O thread: Failed reading log event, reconnecting to retry, log 'mysql-bin.001050' at postion 4

These occur once on every new binary log from the master. In other words, this pair of entries exist in the mysqld log file for mysql-bin.001049, mysql-bin.001048, etc.

The slave threads are running [IO and SQL].

The server-id on the master is 1001 and on the slave is 2001.
The master has binlog-do-db=a,b
the slave has replicated-do-db=a

The master MySQL version: 5.1.40sp1-enterprise-gpl-advanced-log
The master OS: Linux x86_64

The slave MySQL version: 5.1.49sp1-enterprise-gpl-advanced-log
the slave OS: Linux x86_64

Any ideas?

Thanks
