BackgroundJob stop ecexution after some time

Hi,

I am using “Hangfire 1.5” with “Hangfire.MongoDB”, MongoDB as a storage.
Sometime It just stops the background process after some time execution. When I am checking the log there is no any error found.

Below is my configuration:

//******************* Imp. Setting for HangFire ************************************************
bool hangfire_use_sql = Convert.ToBoolean(ConfigurationManager.AppSettings[“is_hangfire_use_sql”]);
if (hangfire_use_sql)
{
var options = new Hangfire.SqlServer.SqlServerStorageOptions
{
PrepareSchemaIfNecessary = true,

                InvisibilityTimeout = TimeSpan.FromHours(2) // default value
            };
            GlobalConfiguration.Configuration
                .UseSqlServerStorage(ConfigurationManager.AppSettings["hangfire_sqldbConnection"].ToString(), options);

        }
        if (!hangfire_use_sql)
        {

            app.UseHangfire(config =>
            {
                config.UseMongoStorage(ConfigurationManager.AppSettings["hangfire_mongodbConnection"].ToString(), ConfigurationManager.AppSettings["hangfire_mongodb"].ToString()
                    , new Hangfire.Mongo.MongoStorageOptions
                    {
                        Prefix = "hf_",
                        InvisibilityTimeout = TimeSpan.FromMinutes(120)
                    });
            });
        }

        app.UseCookieAuthentication(new CookieAuthenticationOptions());

        var dashboardOptions = new DashboardOptions()
        {
           
            AuthorizationFilters = new[] { new MyRestrictiveAuthorizationFilter() }
        };

        app.UseHangfireDashboard("/hangfire",dashboardOptions);

        var backgroundJobServerOptions = new BackgroundJobServerOptions
        {
            ServerName = String.Format("{0}_{1}",Environment.MachineName,Guid.NewGuid().ToString())
        };
        app.UseHangfireServer(backgroundJobServerOptions);

        //*********************************************************************************************

Please suggest help as I am stuck in production environment.
