自己最近写的一组日志处理类(支持高并发处理)

下面的日志处理我在3000个线程同时调用,写20个文件,相当于每个文件150个线程不间断大规模写.没问题,我提高到10000时,出了问题,但不是日志代码的问题,而是系统创建新的线程时报错,建到3500个线程的时候出现问题.后面我会贴出测试代码.

1)FileLogWorker

[csharp]
/// <summary>
    /// 文件日志处理类,利用队列机制，让写日志调用和日志写到文件分离，调用
    /// 方将要写的日志和目标文件插入到日志队列中去就返回，
    /// 然后由内置线程去写到文件里去。这里用了单例模式。
    /// </summary>
    public class FileLogWorker
    {
        private Queue<string> _logCaches = null;
        private Thread _writerThread = null;
        private StreamWriter _streamWriter;
        public string FilePath {get;private set;}
        public Thread LogWriteThread { get { return _writerThread; } }
        public FileLogWorker(string FilePath)
        {
            this.FilePath = FilePath;
            _logCaches = new Queue<string>();
            _writerThread = new Thread(new ThreadStart(WriteLogToFile));
            FStop = false;
            _streamWriter = new StreamWriter(FilePath,true);

                        //队列操作时需要锁定，否则会报错.队列并不是线程安全的.
                        //但多个队列可以同时写.

                    SysAppEventWriter.WriteEvent(-1, ex.Message, System.Diagnostics.EventLogEntryType.Error);
                }

            }
        }
