我们的 httpd/error_log 中充斥着类似这样的消息
[ pid=9705 thr=140631357052896 file=ext/apache2/Hooks.cpp:784 time=2014-09-13 10:18:10.379 ]: Either the vistor clicked on the 'Stop' button in the web browser, or the visitor's connection has stalled and couldn't receive the data that Apache is sending to it. As a result, you will probably see a 'Broken Pipe' error in this log file. Please ignore it, this is normal. You might also want to increase Apache's TimeOut configuration option if you experience this problem often.

这些消息是来自 Apache 吗？（/usr/sbin/httpd -v=> Server version: Apache/2.2.15 (Unix)）
我们如何才能阻止 apache 写入这些消息，而不会丢失其他可能更相关的消息？
或者我们如何才能发现超时设置是否真的存在问题？
