流星消耗大量的Mongo连接 [英] Meteor consuming huge number of Mongo connections

问题描述

过去几周我们一直在生产此问题.

We've been having this issue in prod for the past few weeks.

每隔几天，与我们的compose.io Mongo数据库的连接数就会激增至近5000，这是连接限制.似乎没有任何特定的触发方式.

Every few days, the number of connections to our compose.io Mongo db spikes to nearly 5000, which is the connection limit. There doesn't appear to be any specific trigger for this behavior.

日志如下:

组合支持告诉我们，这几乎肯定是MongoDB驱动程序存在的问题，我们应该使用连接池.我们需要实现流星连接池的一些配置吗?

Compose support tells us that this is almost certainly an issue with the MongoDB driver, and that we should be using connection pooling. Is there some configuration of the Meteor connection pool that we need to implement?

推荐答案

这是Meteor 1.7的问题，已通过流星更新解决. V. 1.8解决了该问题.

This was an issue with Meteor 1.7, resolved by meteor update. V. 1.8 fixes the issue.

这篇关于流星消耗大量的Mongo连接的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
