Tomcat服务器执行一段时间后，报错Error parsing HTTP request header

信息: Error parsing HTTP request header

Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.

java.lang.IllegalArgumentException: Invalid character found in method name. HTTP method names must be tokens

请问是什么原因？该怎么解决啊？

百度搜到说，要在server.xml中，设置并加大maxHttpHeaderSize的属性和值，但试了下，貌似没什么用啊！
