3 copy of this log over time, db being written to the log data inside it, under the new copy binlog to the next / tmp.
Then again copy once binlog, and then parse

Three kinds of programs have reported the same mistake. Mysql version 5.5.25a. linux environment centos6.0
How to fix this problem, more strange?
A friend suggested direct mysql data directory under test with mysqlbinlog
[root@xxxdb0402 data]# /opt/mysql/product/5.5.25a/bin/mysqlbinlog -f mysql-bin.004271 > 4.log
ERROR: Error in Log_event::read_log_event(): 'read error', data_len: 438, event_type: 2
The result is still the same error.
