阿里云上弄了一个tomcat，经常半夜发送崩溃，查看日志发现这个东西，查阅资料发现是Tomcat的header缓冲区大小不够,只需要在server.xml中增加maxHttpHeaderSize字段即可:

<Connector URIEncoding="UTF-8" port="8080" protocol="org.apache.coyote.http11.Http11NioProtocol"
    useBodyEncodingForURI="false"
    enableLookups="false"
               connectionTimeout="20000"
               redirectPort="8443" maxHttpHeaderSize="你想要的大小"/>

如：

   <Connector port="8080" executor="tomcatThreadPool"
     protocol="HTTP/1.1"
     maxThreads="1000"
     maxHttpHeaderSize="8192"
     minSpareThreads="100"
     maxSpareThreads="200"
     acceptCount="1000"
     maxConnections="1000"
     connectionTimeout="30000"
     keepAliveTimeout="15000"
     maxKeepAliveRequests="1"
      tcpNoDelay="true"
     redirectPort="8443"
     enableLookups="false"
     URIEncoding="UTF-8"/>
