可以通過設置：
BooleanQuery.setMaxClauseCount(10000);
來解決問題，但是這樣帶來的問題是會使得內存開銷加大。容易出現OutOfMemory的異常
所以需要非常謹慎處理。
查詢MySQL會出現："java.sql.SQLException: Server shutdown in progress"的異常
問題原因：數據有自動腳本，會將執行時間超過30秒的進程殺掉。
這樣的話，Java的應用就會拋出這樣的異常。
CAS Server 3.1 M2 Released
CAS Server and Client 3.1 Milestone 1 Released
phpCAS 0.5.0 RC5 Release
CAS 3.0.7 Final Release

CAS 3.0.6 Final
這里面有幾個更新很重要：
1.Upgrade to Spring 2.0.1, Spring Web Flow 1.0 and Spring LDAP 1.1.1
2.Introduction of JBossCacheTicketRegistry
支持后JBossCacheTicketRegistry就可以方便大并發量的網站的水平擴展問題。
