几次成功运行后，日志传送还原作业失败

如何解决几次成功运行后，日志传送还原作业失败

我在几个运行良好的数据库上进行了日志传送，但有三个失败了。他们都从同一个小学转到同一个中学。我已经将工作数据库的设置模拟到了非工作数据库。

我重置删除并重置失败数据库的日志传送，并且恢复正常工作，前几次应该如此。但通常在第三个周期它会在作业历史记录中发布断开连接的用户，然后从那时起它会出错。作业成功完成，但在还原步骤中出错。

我在这里错过了什么？错误发生后，我运行完整备份并恢复使其处于待机模式，然后下一个日志传送周期成功。但是第二个循环又失败了

我重建了日志传送并禁用了第二个日志备份作业。得到新的错误。 2021-01-27 07:18:04.37 *** 错误：无法将日志备份文件“\secondary\sqlLogShip\dbname_20210126204500.trn”应用到辅助数据库“dbname”。（Microsoft.sqlServer.Management.LogShipping）*** 2021-01-27 07:18:04.37 *** 错误：处理数据库“dbname”的日志时出错。如果可能，从备份中恢复。如果备份不可用，则可能需要重建日志。恢复期间发生错误，导致数据库“DP_Rpt”(19:0) 无法重新启动。诊断恢复错误并修复它们，或从已知良好的备份中恢复。如果未纠正或预期错误，请联系技术支持。 RESTORE LOG 异常终止。已处理数据库 'dbname' 的 0 页，文件 1 上的文件 'dbname'。已处理数据库“dbname”的 1 页，文件 1 上的文件“dbname”。（.Net sqlClient 数据提供程序）*** 2021-01-27 07:18:04.39 *** 错误：无法记录历史记录/错误消息。（Microsoft.sqlServer.Management.LogShipping）***

这是怎么回事？我有几个登录的数据库，它们运行得很好，但这个有问题。

每天运行完整备份作业是否会导致此问题？
