In my web application, the following query throws an error and causes my application to stop seeing the database server, which causes me to have to restart my application server. Then I put the whole log so you can analyze the case:

ERROR 2023-03-17 12:38:00,638 [210 ] oft.EntityFrameworkCore.Database.Command - Failed executing DbCommand (0ms) [Parameters=[@__ef_filter__p_0='?' (DbType = Boolean), @__ef_filter__p_1='?'

Where I put the x, is our database server IP

I would appreciate any help you can give me.

    Hi @mpineiro

    Sorry for my late reply. Somehow, your question is not listed on support website for us until today. Do you have any SingleAsync usage in your code ? It might be related to https://github.com/dotnet/SqlClient/pull/285.

    Could you also share the previous log line which might show which method is executed and caused this problem ?

    Thanks,

    Hi @ismcagdas

    Thanks for your answer. We do not use SingleAsync and the queries shown in the shared log are NET ZERO's own, they are not our queries. I ask you to follow the case and give us a prompt solution because it is very critical for our business.
