.Net Windows 服务内存不足异常

请告诉我如何解决以下错误。以下内存不足异常仅在代码部署在生产计算机中（即 Windows 服务在生产计算机上启动并运行时）出现。它不会在我们的本地复制。

我们在Windows服务中运行了一个计时器。

请在下面找到代码

        protected override void OnStart(string[] args)
        {
            if (wcfserviceHost != null)
                wcfserviceHost.Close();
            wcfserviceHost = new ServiceHost(typeof(AnalysisManager));
            wcfserviceHost.Open();
            Deletefile();
        }
        protected void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
        {
            Deletefile();
        }
        private void Deletefile()
        {
            try
            {
                timer = new System.Timers.Timer();
                timer.Interval = (1000) * 60 * 60;//(10000) * 6;
                timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed);
                string FilePath = System.Configuration.ConfigurationSettings.AppSettings["FilePath"];
                DirectoryInfo dirInfo = new DirectoryInfo(FilePath);
                foreach (DirectoryInfo subDirectory in dirInfo.GetDirectories())
                {
                    if (subDirectory.Name == "Temp") continue;
                    if (subDirectory.CreationTime < DateTime.Now.AddDays(-1))
                    {
                    subDirectory.Delete(true);
                    }
                }
                timer.Enabled = true;
                timer.Start();
            }
            catch(Exception ex)
            {
            }
        }
    }
}

提前感谢您的帮助。
