我已经安装了CouchDB 2.0，在Ubuntu 16.04上运行，单节点。我的应用程序的一个特殊方面是写入负载，但我希望读取需要及时，因此我希望使用update_notification来重建每n次写入的索引。
我创建了一个小型NodeJS应用程序来处理这个问题，但发现每次编辑设计文档时，我的服务器都会崩溃。结果是因为CouchDB发布了数百个更新侦听器副本，而这似乎是因为couch.log中报告的崩溃。每次发生崩溃时，都会生成一个新的更新侦听器，但旧脚本没有终止。
我已经把这个简化为一个简单的案例，其中update_notification处理者除了记录从STDIN收到的更新外什么都不做：
updates.bash：
#!/bin/bash
while read -r line
do
echo "$line" >> /home/www/logs/updates.log
done
local.ini：
[update_notification]
updates=/home/www/updates.bash
我希望看到updates.log填写像......
{"type":"updated","db":"transactions"}
{"type":"ddoc_updated","db":"transactions","id":"_design/temp"}
......这就是CouchDB 1.6.1上的内容。但是在CouchDB 2.0上，我看到我的couch.log填充了数百个崩溃报告，并且我的更新脚本反复重新生成。
