发送实体时 Orion 随机下降
Orion goes down randomly when send entities
我已经在一台新机器上安装了 Orion，使用 yum 软件包并按照管理指南中的说明安装 mongodb。
此外，我已经从 wirecloud 部署了一个 orion 实例，并将我的旧 Orion 实例从 0.21 更新到 0.22。
在所有情况下，Orion 都会随机下降，我不知道为什么。 0.21版本完美运行，但现在非常不稳定
我安装了一个 cron 任务来检查 Orion 是否有 PID 死机，然后重新启动它，但问题是有时我的 Orion 实例会停机 1 分钟。
我这样发送请求：
(curl http://my.orion.instance.es:1026/v1/updateContext -s -S --header 'Content-Type: application/json' --header 'Accept: application/json' -d @- | python -mjson.tool) <<EOF
{
"contextElements": [
{
"type": "Alert",
"isPattern": "false",
"id": "myemail@dot.com",
"attributes": [
{
"name": "alert-type",
"type": "text",
"value": "10020"
},{
"name": "message",
"type": "text",
"value": "Flooding"
},{
"name": "status",
"type": "text",
"value": "100"
},{
"name": "gateway",
"type": "text",
"value": "5"
}
]
}
],
"updateAction": "APPEND"
}
EOF
响应是：
{
"contextResponses": [
{
"contextElement": {
"attributes": [
{
"name": "alert-type",
"type": "text",
"value": ""
},
{
"name": "message",
"type": "text",
"value": ""
},
{
"name": "status",
"type": "text",
"value": ""
},
{
"name": "gateway",
"type": "text",
"value": ""
}
],
"id": "myemail@dot.com",
"isPattern": "false",
"type": "Alert"
},
"statusCode": {
"code": "200",
"reasonPhrase": "OK"
}
}
]
}
此时，Orion 出现故障（如果我发送 UPDATE 或 DELETE 也会发生）。
我有 ngsi2cosmos 运行，并显示这些消息（也许问题出在这里）：
INFO in requests_wrappers [/root/ngsi2cosmos/requests_wrappers.py:58]:

我该如何解决这个问题？
编辑：

显示正常运行时间的 /version 的屏幕截图（在此之前，正常运行时间是 5 天，但是当我开始使用混搭时，出现了问题，Orion 宕机了）。
编辑 2：
安装gdb，执行ulimit -c unlimited
运行 contextBroker -fg
现在 shell 显示更详细的错误：

这个问题的原因是this issue that has been already solved in the developed branch, also related with this 。修复将随 Orion 0.23.0 版本一起提供。
作为临时解决方法，您可以在订阅的 reference 字段中使用 IP 而不是主机名。
我已经在一台新机器上安装了 Orion，使用 yum 软件包并按照管理指南中的说明安装 mongodb。
此外，我已经从 wirecloud 部署了一个 orion 实例，并将我的旧 Orion 实例从 0.21 更新到 0.22。
在所有情况下，Orion 都会随机下降，我不知道为什么。 0.21版本完美运行，但现在非常不稳定
我安装了一个 cron 任务来检查 Orion 是否有 PID 死机，然后重新启动它，但问题是有时我的 Orion 实例会停机 1 分钟。
我这样发送请求：
(curl http://my.orion.instance.es:1026/v1/updateContext -s -S --header 'Content-Type: application/json' --header 'Accept: application/json' -d @- | python -mjson.tool) <<EOF
{
"contextElements": [
{
"type": "Alert",
"isPattern": "false",
"id": "myemail@dot.com",
"attributes": [
{
"name": "alert-type",
"type": "text",
"value": "10020"
},{
"name": "message",
"type": "text",
"value": "Flooding"
},{
"name": "status",
"type": "text",
"value": "100"
},{
"name": "gateway",
"type": "text",
"value": "5"
}
]
}
],
"updateAction": "APPEND"
}
EOF
响应是：
{
"contextResponses": [
{
"contextElement": {
"attributes": [
{
"name": "alert-type",
"type": "text",
"value": ""
},
{
"name": "message",
"type": "text",
"value": ""
},
{
"name": "status",
"type": "text",
"value": ""
},
{
"name": "gateway",
"type": "text",
"value": ""
}
],
"id": "myemail@dot.com",
"isPattern": "false",
"type": "Alert"
},
"statusCode": {
"code": "200",
"reasonPhrase": "OK"
}
}
]
}
此时，Orion 出现故障（如果我发送 UPDATE 或 DELETE 也会发生）。
我有 ngsi2cosmos 运行，并显示这些消息（也许问题出在这里）：
INFO in requests_wrappers [/root/ngsi2cosmos/requests_wrappers.py:58]:

我该如何解决这个问题？
