note The full stack trace of the root cause is available in the Apache Tomcat/6.0.18 logs.

这是我的 Spring LDAP 设置

<property name="baseEnvironmentProperties">
    <props>
        <prop key="com.sun.jndi.ldap.connect.pool">true</prop>
        <prop key="com.sun.jndi.ldap.connect.pool.initsize">1</prop>
        <prop key="com.sun.jndi.ldap.connect.pool.maxsize">1</prop>
        <prop key="com.sun.jndi.ldap.connect.pool.prefsize">1</prop>
    <prop key="com.sun.jndi.ldap.connect.pool.timeout">300000</prop>
    </props>
</property>

任何评论为什么会导致内存不足？我的池大小只有 1？

Answer 1

我怀疑它与 LDAP 或您的池大小有任何关系。烫发一代可能会被填满。我会打开 VisualVM 并观察应用程序启动时内存发生的情况，看看情况是否如此。

我还会检查 Tomcat 日志，看看是否有比此堆栈跟踪更多、更好的信息。
