在3.0.2版的etc配置文件中没有找到TrafficServer管理员指南中提到的“filter.config”这个文件，请问这个文件中需要添加的一些选项应该在哪里添加
我测试Prefetch模块，发现Prefetch模块会发生段错误，
ab -n 1 -c 1 -X 192.168.16.198:8080 -d http://club.baobao.sohu.com/r-mmbb-3954004-0-29-900.html
访问上面的页面，每次都会发生。在traffic server官网，没有查到这个问题
配置方面：在records.config中使能Prefetch，在Prefetch.config中配置child，

可以回复了。。
不能回复么？
不能回复么？
是用的trunk吗？我印象中trunk做了很多server session管理方面的改进，包括进程间fd io方面的改进。
TS-924
TS-857 TS-934 TS-1031
你的问题可能比较纠结
我在traffic_shell中运行时，出现如下提示
% show:cache-stats
ERROR: Invalid parameter specified.
Check parameters for correct syntax and type.
Bytes Used --- 0 GB
Cache Size --- 10 GB
--RAM Cache--
Total Bytes -- 13934592
Bytes Used --- 135168
请问ERROR: Invalid parameter specified.
Check parameters for correct syntax and type.
是什么错误

3.0.1和3.0.2都有这个问题，配置会影响到这个问题
CONFIG proxy.config.prefetch.default_url_proto STRING tcp
CONFIG proxy.config.prefetch.default_data_proto STRING tcp
按照上面的配置，会出现上面的段错误
CONFIG proxy.config.prefetch.default_url_proto STRING udp
CONFIG proxy.config.prefetch.default_data_proto STRING udp
按照这个配置，不会出现段错误
使用上面的任何一个配置，都会出现另外一个问题：内存占用迅速增加
使用udp时，资源会被迅速耗尽，最终会因内存被耗尽崩溃
traffic server有没有检查资源使用情况的方法呀？如何追踪内存使用呀？
使用valgrind之类的工具误报很严重呀
