我是Wildfly（Jboss）的新手，我的新工作遇到了麻烦。
服务器写了很多警告

我读过这篇文章：http://www.postgresql.org/docs/9.2/static/sql-prepare-transaction.html
据我所知，准备好的事务是系统首先在硬盘驱动器上写入然后提交或回滚的事务。 并且需谨慎，因为它消耗了大量的系统资源，并可能导致问题。 我认为Server做了很多这样的事务，但是不提交/回滚它们并且它保存系统资源（正如我们在warn消息中看到的那样）然后服务器失败，因为没有更多的免费资源（＆＃34;太多的打开文件＆ ＃34）。 但为什么服务器这样做？为什么它会使很多这种交易消耗所有资源？ 它意味着什么＆＃34;准备好的交易属于另一个数据库＆＃34; ？ 怎么会蜂？ 我不知道如何解决这个问题！ 我希望对你有所帮助！谢谢！
