遇到一个很奇怪的问题，使用mosdns一段时间后DNS解析就会出问题

[Deskfrest]

家里使用移动宽带。使用passwall指定mosdns为上游，正常使用几天后。就会遇到浏览器打开国内外网页报DNS有问题，telegram因为用的ip所以可以正常使用。尝试手动点击基本设置-api选项-刷新缓存后测试。也无法正常打开网页。

将mosdns停用几分钟后，重新启动，重新指定passwall上游为mosdns后，又可以正常使用了。

有遇到和我类似情况的么

同样问题，随机2个上游DNS都不可用会触发，换用smartdns了

这个随机上游是指的国内还是国外DNS啊？我目前国内设置了2个，国外设置了2个。意思是4个同时不能用就会触发这个问题么？因为只要出现这个问题的时候无论是国内还是国外，网站都会出现DNS有问题

我这个问题也与这相似吗？mosdns设置在ADGH上游，即MOSDNS国内直接查询，国外走代理查询，只做分流用，每过一段时间，ADGH的日志里就有MOSDNS拒绝响应的报错日志。
