Question

我有12个调制解调器连接到我的HylaFax服务器，看来有时我的一些调制解调器卡在“发送作业”状态，直到我从调制解调器断开线路以使作业死亡。

调制解调器可以在没有任何通知的情况下永远保持这种状态，这就是我在服务器跟踪中获得的工作被卡住了：

据我所知，调制解调器正在等待（永远）远程传真进行响应。

服务器配置为：HylaFax 6.0.6 / CentOS 6.3

问题是：

在Hylafax中是否有任何配置参数可以避免这种冻结？
作为一个快速的解决方法，我可以编写一个脚本来监视发送作业并杀死一个持续在“发送作业”中的作业，但我还是找不到杀死正在运行的作业（不是排队的作业）

Answer 1

在使用手机开发时，我只有一些光线接触传真，但我了解到传真是一个“测试，测试，测试”问题，需要付出很多努力（当通过GSM运行传真代码时）在某些情况下，由于某些不可能的时间问题，我不得不开始发送回复信息。即使您根据规范实现了所有内容，也无法保证工作正常。今天大多数（全部？）移动网络和电话都有理由放弃对传真的支持。

据我所知，调制解调器正在等待（永远）远程传真进行响应。

情况可能如此，据我所知，可能无论是远程传真机还是hylafax都没有责任。实施一些监控服务似乎是解决这个问题的唯一合理可靠的方法。

Hylafax调制解调器处于“发送作业”状态
