Tomcat
問題描述：
我的網站應用執行三五天後，web就無法訪問了；進入伺服器用top命令檢視系統資源，
cpu佔用率100%，sleeping程式達到了1000多個，Tomcat後臺丟擲以下錯誤:

透過以上分析，Tomcat在後臺一直新建了非常多的程式，但是用過的程式為什麼不能再重新使用或回收能，這點我很不明白;
我檢查資料庫操作的程式，ResultSet 和Connection都有關閉。
目前沒找出問題所在，請各位高手指點，非常感謝！！
伺服器環境：
RedHat Linux7.2+Apache1.3+mod_jk-1.3-noeapi.so+Tomcat4.06+Oracle
CPU兩個，RAM:2G SWAP:2G
應用技術架構：jsp+JavaBean+Oracle
Apache的httpd.conf主要配置:
Timeout 300
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 15
MinSpareServers 5
MaxSpareServers 20
StartServers 8
MaxClients 360
MaxRequestsPerChild 0
Tomcat的主要配置：
在catalina.sh加了JAVA_OPTS="-Xms1024m -Xmx1640m"（設定JVM最大記憶體）
Server.xml的主要配置如下：
<Connector className="org.apache.ajp.tomcat4.Ajp13Connector"
port="8009" minProcessors="5" maxProcessors="100"
acceptCount="10" debug="0"/>
使用Tomcat自帶的連線池，連線池配置如下：
<parameter>
<name>removeAbandoned</name>
<value>true</value>
</parameter>
<parameter>
<name>removeAbandonedTimeout</name>
<value>10</value>
</parameter>
<parameter>
<name>maxActive</name>
<value>100</value>
</parameter>
<parameter>
<name>maxIdle</name>
<value>30</value>
</parameter>
<parameter>
<name>maxWait</name>
<value>9000</value>
</parameter>
