星号间歇性3秒音频丢失，日志乱序

时间：2014-08-20 22:32:28

标签： asterisk

我有一个Asterisk服务器，为450多个代理商提供服务，它已经投入生产一年多一点。每隔一段时间我们就会遇到3秒钟丢失音频，然后是1秒的乱码音频。流数据和Wireshark回放显示它来自该系统。今天发现的症状是，在这些短暂的音频问题期间，日志记录无序，这是时间戳中的第二个向前和向后跳跃。在RTP捕获中，1秒的乱码音频包含许多错误的时间戳＆＃34;标记。

在下面的日志中，您会看到它在12:20:45到12:20:48之间跳转。

环境：

  • VMware HA群集，大约50个虚拟机的服务
  • ESXi 5.1
  • 没有过度承诺的资源＆amp; CPU /磁盘IO分配设置为“高”＆＃39;对于此VM
  • CentOS 6.5
  • Asterisk C.3.7.2（商业版，1.4主干）
  • vmware-tools是最新的
  • 主机时间同步，而不是NTPd

我没有看到vCenter给我带来的历史或实时统计中的任何有趣的东西，尽管我完全承认我可能正在寻找所有错误的地方。另外，这些3秒异常可能在图表中平均。

我假设任何导致日志失序的因素也会导致音频丢失。我一直无法在搜索中找到任何对无序日志条目的引用。有没有人遇到过这个问题？

1 个答案:

答案 0 :(得分：1)

看起来问题与时间重新同步。 Asterisk没有考虑到时间变化的可能性，因为它设计用于通用硬件。

可以建议以下

1）摆脱vmware，放在硬件主机上

OR

2）禁用主机时间同步，改为使用ntp。增加主机的cpu资源。
