以下是堆栈跟踪.我读到“管道破裂”是由于未关闭连接8个小时,并且该连接自动关闭.我看到此http://itellity.wordpress.com/2011/05/18/getting-rid-of-socketexception-broken-pipe-with-quartz-and-mysql-on-jboss/.无法在本地计算机上复制.
>有什么方法可以在本地计算机上重现此内容.
>这样会不会造成崩溃？我使用的是石英罐1.6.5和tomcat 6.0.18的旧版本.这会是一个问题吗？
请帮助我解决此问题.

编辑：
我在用
org.quartz.dataSource.QUARTZ_NO_TX.validateOnCheckout = true
org.quartz.dataSource.QUARTZ_NO_TX.validationQuery = select 1
在我的石英性能上
autoreconnect=true
有什么办法可以通过更改mysql属性来重现此内容.我只在我的服务器上得到它.
解决方法:
我相信这与8小时后删除的MySQL stale connection有关.

阅读this文章.
确保您具有以下设置(不确定确切的属性名称,但它们应与下面提到的相似)
> testWhileIdle = true
> validationQuery =“ SELECT 1”
> minEvictableIdleTimeMillis = 1800000
> timeBetween EvictionRunsMillis = 1800000
> numTestsPerEvictionRun = 3
