不知道apache错误日志中的报错指的是什么

我的apache/logs/error_log日志有大量以下信息：

不知道是为什么？

我做了apache和tomcat的整合，用的是jk2，会是这个的问题吗？但是功能我测试已经实现了

这是正常信息,关闭debug,就没了

我现在的日志级别是LogLevel warn，可是还是有notice的输出，还是error log的级别在别的地方设置？

notice信息不是apache写的,是其它的程序写上去的

这里就是Jk写上去的了

看看JkLogLevel是啥

是不是应该加上这些：

JkWorkersFile /usr/local/apache/conf/workers2.properties
JkLogFile     /var/log/jklog/mod_jk.log
JkLogLevel error

但是加上后，重启apache，就报如下错误：

Syntax error on line 413 of /usr/local/apache/conf/httpd.conf:
Invalid command 'JkWorkersFile', perhaps misspelled or defined by a module not included in the server configuration
httpd not running, trying to start

我也load的了：LoadModule jk2_module modules/mod_jk2.so，为什么还会报错呢？

问题解决了！！！
是在workers2.properties中修改。
谢谢 hmglly ！！！

我还想问一个问题：
    我没有在tomcat/conf/下建立 jk2.properties 配置文件，为什么也能实现功能呢？
