Hello all,

  I was wondering if someone could shed some light on this problem I'm 
having.  I have 3 slave MySQL servers replication from a master 
machine.  The master machine is running only MySQL while the slave 
machines are an Apache + Tomcat + MySQL web service.  All slave 
machines are precisely identical.  I'm running into a situation where 
(seemly at random) after a month or two of consistently flawless 
performance, just ONE of the slave machines will report the following 
error in the .err log:

030807  9:22:35  Error in Log_event::read_log_event(): 
        'Event too big', data_len=1869425764,event_type=114
030807  9:22:35  Error reading relay log event: slave SQL thread 
        aborted because of I/O error
030807  9:22:35  Could not parse log event entry, check the master 
        for binlog corruption This may also be a network problem, 
        or just a bug in the master or slave code.
030807  9:22:35  Error running query, slave SQL thread aborted. Fix 
        the problem, and restart the slave SQL thread with "SLAVE START". 
        We stopped at log 'oakpub-bin.002' position 25239274

However the other two slaves are up-to-date on replication with no error 
messages and mysqlbinlog output shows no obvious malformed statements.  
This problem is not specific to just one machine but has happened on 
all 3 slave nodes in the past few months.  Trying to restart the slave 
process results in the same error.  Manually performing the statement 
in the binlog works fine and then the slave can be played forward to 
the current master logfile location with no problems.  I've also tried 
deleting the entire database on the slave and recreating everything 
with LOAD DATA FROM MASTER and that goes smoothly as well.

  I cannot reproduce this behavior as it's intermittent.  Any thoughts?

Thanks,
Jason
