[chrisyip]

when starting new tasks, xunlei-lixian throws this error:

你的系统多大内存？看起来像是内存不足。

[chrisyip]

ac66u 内存应该够的，重启一下就好很多了。

[iambus]

重启之后还有什么问题？

[chrisyip]

暂时没发现有问题。

[iambus]

那如果有别的问题就重新提交一个新的issue吧。 另外你后来贴的那个“Invalid response”是服务器不稳定造成的。最新的代码会忽略然后重试。

[chrisyip]

在下载单个多文件 BT 离线任务时，特别容易出现这个问题，而设备内存量和上图差不多。

测试下载两个 4GB 只有一个 DMG 文件的 BT 是没有问题，但是下载一个 4GB 的视频合集（每个约 300MB）时，就会出错，只能通过重启路由才能恢复正常。

注：已更新到最新版。

[iambus]

用top之类的命令检查一下具体的内存使用。

[chrisyip]

发起 lx list 时也会报内存错：

看剩余内存应该足够了的样子。要不然你盯着top看下运行lx list时，对应python进程的内存使用？

[jzmno1]

机皇啊，我还是hg320.梅林版有shibby大大的tomato好用？

[chrisyip]

@jzmno1 merlin 最大的优点就是从 ASUS 官方改过来的，有着先天的优势，比如 Web UI 的 ED2K、BT 下载工具，比如文件共享。可以说你只管刷就行了，不必折腾 aria2 之类也能满足常见需求。

我也尝试过清理一下内存，用的是这页面介绍的方法：http://blog.midnightmonk.com/225/linux/free-up-and-release-unused-or-cached-memory.shtml，但是无效。

其实我感觉这并不是路由和固件的问题，毕竟可用内存是摆在那，更有可能是程序使用内存时有错。

在路由器里启动一个python的shell，然后运行s = 'x' * 10000000看看是否出错：

$ python
Python 2.7.3 (default, Sep 26 2012, 21:53:58)
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> s = 'x' * 10000000
>>>

正常执行，没有出错。

[iambus]

那就无法可解了。最多你把路由器的IP和登陆账号发给我上去亲自试试，或许能注意到点什么。
