我执行从PHP 5.4到Mongo 2.4.10的“findOne（）”查询
PHP mongo驱动程序版本是1.5.5
Mongo DB是replicaset
要限制等待此“findOne（）”查询的结果，我使用“socketTimeoutMS”选项
根据文件超过“socketTimeoutMS”函数“findOne（）”必须抛出“MongoCursorTimeoutException”异常
但我没有在日志中看到任何异常
此外，我还测量了这个“findOne（）”查询的执行时间 - 通常比“socketTimeoutMS”更多（有时是几次）
所以看起来“socketTimeoutMS”选项不起作用 需要提一下的是我们的mongo DB负载很高
还需要提一下，在我的本地机器上“socketTimeoutMS”工作正常
那么“socketTimeoutMS”选项对生产无知的原因是什么？
