Question

我有一个带有PHP Thruway工作人员的Crossbar.io服务器。最近，我开始收到以下错误。它现在每天发生一次：

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

有人知道热，以防止这种情况吗？

如果失败，如何在这种情况下自动重启工作人员？

Answer 1

我在linux中使用MONIT检查crossbar-controler进程并添加以下行解决了它：

如果孩子＆lt; 3然后重新启动

3是crossbar-controler对我的环境具有的os子进程数。如果它们中的任何一个退出，那么crossbar会重新启动并通知我。您必须检查已运行的子进程数：

sudo service crossbar status。

这解决了错误退出工作程序，但需要重新启动crossbar-controler。我确信必须是解决问题的横杆/高速路。理想的方法是尝试捕获php的所有可能错误，以防止致命的工作人员退出。
