mysql oom之后，重启时发生
130517 16:00:10  InnoDB: Error: page 447 log sequence number 292344272
InnoDB: is in the future! Current system log sequence number 1595916.
InnoDB: Your database may be corrupt or you may have copied the InnoDB
InnoDB: tablespace but not the InnoDB log files. 
两次了，只有一台vm有这个问题，好奇怪。。
