.NET 核心工作者服务冻结

[英].NET Core worker service freezing

原文 2022-01-05 08:12:35 8 1 c#/ .net-core/ service

We have a long running .net core worker service which has been in production for over 6 months now without any problem.我们有一个长期运行的 .net 核心工作者服务，该服务已经投入生产超过 6 个月，现在没有任何问题。 Now 2nd of January it just froze after midnight and just stood there doing nothing.现在 1 月 2 日午夜刚过就结冰了，只是站在那里无所事事。

We have daily log file and 1. day has last entry at 2022-01-01T23:15:38.我们有每日日志文件，并且 1. day 的最后一个条目是 2022-01-01T23:15:38。 Second day doesn't have logfile at all.第二天根本没有日志文件。

As the service is "running" our monitoring didn't notice anything wrong.由于服务正在“运行”，我们的监控没有发现任何错误。

So on third days morning we notice that our service is frozen and restart it.所以在第三天早上我们注意到我们的服务被冻结并重新启动它。 Fourth day it works as intended until midnight, last entry in log is 2022-01-04T23:47:55 and service has frozen again.第四天它按预期工作到午夜，日志中的最后一个条目是 2022-01-04T23:47:55 并且服务再次冻结。 No log file for 5th day, until I restart it again.第 5 天没有日志文件，直到我再次重新启动它。

So has anyone experienced similar behavior?那么有没有人经历过类似的行为？
