Replication issue

[Michael T. Babcock]

I'm replicating over a local SSH tunnel to a remote machine ... both 
MySQL instances have been working fine in the past (and both have their 
own binary logs, and only one database is being replicated between the 
two).  I'm getting this in the error logs:

021030 13:13:25  Slave: connected to master 'x@stripped:3303',  
replication started in log 'FIRST' at position 6281
021030 13:13:25  Slave: received 0 length packet from server, apparent 
master shutdown:
021030 13:13:25  Slave: Failed reading log event, reconnecting to retry, 
log 'FIRST' position 6281
021030 13:13:25  Slave: reconnected to master 
'x@stripped:3303',replication resumed in log 'FIRST' at position 6281
021030 13:13:25  Slave: received 0 length packet from server, apparent 
master shutdown:
021030 13:14:25  Slave: Failed reading log event, reconnecting to retry, 
log 'FIRST' position 6281

SSH is showing this:
