测试关于“汉字”更新数据
后台抛出 =INFO REPORT==== 2010-10-25 18:07:47 ===
D(<0.1906.0>:ejabberd_odbc:416) : MySQL, Send query
["UPDATE vendors SET vendorname='",[20013],"' WHERE vendorid='","37","';"]
=INFO REPORT==== 2010-10-25 18:07:52 ===
D(<0.1906.0>:ejabberd_odbc:416) : MySQL, Send query
"rollback;"
解决方法：
[20013] 是为调用了xmerl:xmerl_scan:string/2 返回的,只好从编码上入手，但 很不能理解 如果 下面参数 S 已经是UTF8 了在执行下面操作后 又进行了编码（为什么再次编码，此现象只出现在汉字上面）。所以只好在针对xmerl_scan:string/2的返回值进行编码，而不能写成通用的方法。 如[233,223,222] 执行下面操作后成了 ［228,123,345,238,222,133］(此数据是说明问题随便写的) > > + UTF8Binary = unicode:characters_to_binary(S, utf8, utf8), > > + UTF8Str = binary_to_list(UTF8Binary),
2.单个 虚拟机 测试（ <client host="client-3.langzhelabdns.com" use_controller_vm="true" maxusers="60000"/>
）
解决方法：以下问题 修改ulimit -n 102400参数解决

3. ------------------------------------------------
根据上面出现的情况 调整ulimit参数后，tsung日志出现 etimedout （ssh验证 tsung监听 ）会出现此问题
参见 http://www.iteye.com/topic/573238部分解释
