Hangfire Processing BackgroundExecution + unclear warning message

Hi,

I have implemented Hangfire with .net core web api using Kestrel. From time to time Hangfire logs the following message: “Execution Worker recovered from the Failed state after 04:02:47.7865149 and is in the Running state now”

Does anyone know what this message is referring to or it’s cause ?

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
   //...

   RegisterHangFireRecurringJob();     
}
        
private static void RegisterHangFireRecurringJob {
        
    RecurringJob.AddOrUpdate<DbRepository>(
       x => x.PerformDatabaseQuery(), Cron.Yearly());
}
