标题: 搬家后经常宕机的问题，请大家看看日志。
之前是一天几次宕机，2分钟自动恢复，貌似是内存耗尽了，我看日志，发现是有个自动更新的程序数据出问题了，然后我就把这个程序和数据库都清空了，之后好多，但是每天还是会偶尔单机一次，下面mysql的错误日志：
  1. 121203 23:20:53 mysqld_safe Number of processes running now: 0
  2. 121203 23:20:54 mysqld_safe mysqld restarted
  3. 121203 23:20:59 [Note] Event Scheduler: Loaded 0 events
  4. 121203 23:20:59 [Note] /usr/local/mysql/libexec/mysqld: ready for connections.
  5. Version: '5.1.60-log'  socket: '/tmp/mysql.sock'  port: 3306  Source distribution
复制代码
下面是宕机时的部分messages，不是全部，还有两段貌似跟这个是一样的，超过帖子限制字数了。

还以为是教学贴，失望了。楼下来。

看来是没内存了，加点虚拟的试试
