org.apache.tomcat.util.net.Nio2Endpoint$Nio2Acceptor.failed 套接字接受失败 解决办法

严重 [http-nio-18090-Acceptor-0] org.apache.tomcat.util.net.NioEndpoint$Acceptor.run Socket accept failed
 java.io.IOException: 打开的文件过多
    at sun.nio.ch.ServerSocketChannelImpl.accept0(Native Method)
    at sun.nio.ch.ServerSocketChannelImpl.accept(ServerSocketChannelImpl.java:422)
    at sun.nio.ch.ServerSocketChannelImpl.accept(ServerSocketChannelImpl.java:250)
    at org.apache.tomcat.util.net.NioEndpoint$Acceptor.run(NioEndpoint.java:692)
    at java.lang.Thread.run(Thread.java:748)

在server.xml中修改如下一段

<Server port="8000" shutdown="SHUTDOWN" debug="0">
    <Service name="Tomcat-Standalone">
        <Connector port="18090" connectionTimeout="20000" redirectPort="8443"
                maxThreads="48" minSpareThreads="10"
                enableLookups="false" acceptCount="1" URIEncoding="UTF-8"
                protocol="org.apache.coyote.http11.Http11NioProtocol" />

修改为：

<Server port="8000" shutdown="SHUTDOWN" debug="0">
    <Service name="Tomcat-Standalone">
        <Connector port="18090" connectionTimeout="20000" redirectPort="8443"
                maxThreads="48" minSpareThreads="10"
                enableLookups="false" acceptCount="100" URIEncoding="UTF-8"
                protocol="org.apache.coyote.http11.Http11NioProtocol" />

将acceptCount="1"修改为acceptCount="100"即可
