Crossbar Thruway工人崩溃

Question

我有一个PHP Thruway工作者的Crossbar.io服务器。最近，我开始收到以下错误。现在大约每天发生一次：

2016-04-17T21:08:12+0000 [Router       9572] Unable to format event {'log_logger': <Logger 'crossbar.router.protocol.WampWebSocketServerProtocol'>, 'log_time': 1460927292.17918, 'log_source': None, 'log_format': 'Traceback (most recent call last):\n  File "/usr/local/lib/python2.7/site-packages/autobahn/wamp/websocket.py", line 88, in onMessage\n    for msg in self._serializer.unserialize(payload, isBinary):\n  File "/usr/local/lib/python2.7/site-packages/autobahn/wamp/serializer.py", line 106, in unserialize\n    raise ProtocolError("invalid serialization of WAMP message ({0})".format(e))\nProtocolError: invalid serialization of WAMP message (Expected object or value)\n'}: tuple index out of range

2016-04-17T21:08:19+0000 [Controller   9565] Guest worker2 exited with error A process has ended with a probable error condition: process ended with exit code 255.

有人知道如何防止这种情况发生吗？

如果worker失败了，我该如何自动重新启动它？

Answer 1

我在linux中解决了这个问题，MONIT检查了crossbar-controler进程，并添加了以下代码行：

如果子进程<3，则重新启动

3是crossbar-controler在我的环境中拥有的子进程数。如果它们中的任何一个退出，那么crossbar会自动重启并通知我。您必须使用以下命令检查正在运行的子进程的数量：

sudo服务交叉开关状态。

这解决了错误退出工作者，但以重新启动纵横制控制器为代价。我确信这一定是一种解决问题的纵横交错的方式。理想的方法是尝试捕获php的所有可能的错误，以防止致命的worker退出。

谢谢
