Remoting 数据流压缩报错

Question

问题遇到的现象和发生背景

在使用Remoting通道压缩的时候借鉴了

代码，一开始使用没有问题，但是偶尔遇到下面的异常情况，错误显示是压缩写入的时候数组越界，但是这是NZlib内部问题吗？我需要怎么解决。实际测试环境根本无法复现，只有生产环境才会出现这样的现象。如果可以通过升级解决的话，得弄清这个原因是啥？

/// <summary>
        /// 压缩数据流
        /// </summary>
        /// <param name="inStream"></param>
        /// <returns></returns>
        public static Stream getCompressedStreamCopy(Stream inStream) 
        {
            MemoryStream outStream = new MemoryStream();
            Deflater mDeflater = new Deflater(Deflater.BEST_COMPRESSION);
            DeflaterOutputStream compressStream = new DeflaterOutputStream(outStream,mDeflater);

            byte[] buf = new Byte[4096];
            int cnt = inStream.Read(buf,0,4096);
            while (cnt>0) {
                compressStream.Write(buf,0,cnt);
                cnt = inStream.Read(buf,0,4096);
            }
            compressStream.Finish();
            outStream.Seek(0,SeekOrigin.Begin);
            return outStream;
        }
