我的邮件服务器是EMOS1.5,ClamAV版本是0.98,最近总是在日志文件里发现如下内容:

从字面看,是建议升级到0.98.1,好像是升级也成功了。但是总是反复出现这消息,反复进行升级操作,好像又没有升级成功。

如此长时间反复出现这些操作,对系统有影响么?前天上午系统就出过问题,登陆不上,收不到邮件,后来ping不通。只有重启才正常。我查看日志,当时我重启机器的时候,正是在自检数据库的过程中,部分日志文件如下:

Apr  9 09:07:15 mailserver kernel: Command line: ro root=/dev/VolGroup00/LogVol00

注意黑体字,那时候机器重启了。

请问这是怎么一回事儿呢?
