最近一段时间linux系统运行一段时间后会出现，系统重启后后恢复正常.

那么究竟是什么原因找不到文件呢！ 明明工程项目都是存在的！

1：文件找不了 我第一想到的是 jboss 下面的/server/default/tmp 是否存在该工程目录。经过查询改目下本没有生成，重启后有没有生成。那么到底临时目前去那里了。我又在linux的tmp看到了 0-ROOT  这个目录里面就是工程的临时文件。

2:linux的tmp每隔一段时间就会被清除。 在  /etc/cron.daily/tmpwatch可以查看到更新的周期

3：那么是什么导致了jboss的临时文件生成在了linux的tmp下  经过查询是

    修改jboss的配置文件server/default/deploy/jboss-web.deployer/context.xml

     在Context元素中添加antiResourceLocking="true" 和  antiJARLocking="true" 属性

上面就是修改热部署的，从而也导致了 jboss的tmp生产到了系统的目录下  去掉即可。

究竟原理有待研究
