实在没办法，binlog日志无法解析出来！
[root@localhost 123]# mysqlbinlog mysql-bin.000227 > 1.sql
ERROR: Error in Log_event::read_log_event(): 'Event too big', data_len: -1291845632, event_type: 1

尝试过的方法：

1.网上查资料说是版本问题，但我这个mysqlbinlog文件为二进制编译安装时候生成的mysqlbinlog文件，而且环境变量也没问题。确认了不是版本问题。
2.该服务器没有做主从。
3.把该mysql-bin.000227 文件或者其他任何一个mysql-bin.xxxxx文件在该机器上或拿到其他服务器上也是安装相同版本的mysql都是报相同的错（见红色部分）。

请各位大牛们帮忙处理一下！小弟在这里先谢了！

------解决方案--------------------
或者调大一下你的 max_allowed_packet 再试试。
------解决方案--------------------
max_allowed_packet 设置的是多大？ 修改大一点试下呢？


mysql log_event.cc 源码中有:
00708 #ifndef max_allowed_packet
00709 THD *thd=current_thd;
00710 uint max_allowed_packet= thd ? thd->variables.max_allowed_packet : ~(ulong)0;
00711 #endif
00712 
00713 if (data_len > max_allowed_packet)
00714 {
00715 error = "Event too big";
00716 goto err;
00717 }

我也网上翻的，没试过，可以尝试一下。
