为什么 mongoDB c# 驱动程序会出现间歇性错误 DnsClient.DnsResponseException: Header id mismatch

Question

我从在 dot net core 上运行的 MongoDB C# 驱动程序间歇性地收到以下错误。所有查询都会失败几分钟，抱怨 DNS 查询错误，然后在几分钟后修复。

DnsClient.DnsResponseException: Header id missmatch.
   at DnsClient.DnsUdpMessageHandler.Query(IPEndPoint server, DnsRequestMessage request, TimeSpan timeout)
   at DnsClient.LookupClient.ResolveQuery(DnsMessageHandler handler, DnsRequestMessage request, Audit continueAudit)
