Hi,
I have 2 setups tomcat5.5.20 on Redhat and mysql 4.1.22 on another Redhat
server.
Recently i started getting the repeating error(each seconds) in catalina.out:
DBCP object created 2010-12-22 13:33:12 by the following code was never closed:
java.lang.Exception

i have to restart tomcat once a day when
server load reaches 80-90%.
Also catalina.out file is growing too fast which every few hours need to clear the logs.
My datasource config:
<bean id="myDataSource"
class="org.apache.tomcat.dbcp.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName">
<value>com.mysql.jdbc.Driver</value>
</property>
jdbc:mysql://XXX/XXX?autoReconnect=true

20
<property name="maxIdle">
<value>50</value>
</property>
<property name="maxActive">
<value>50</value>
</property>
<property name="removeAbandoned">
<value>false</value>
</property>
<property name="removeAbandonedTimeout">

</property>
<property name="username">
<value>XXX</value>
</property>
<property name="password">

</property>
</bean>
Any idea what can be the issue ?
Thanks for any direction.
