延迟作业服务在其启动时间不到 1 小时后停止,并显示以下日志:

This probably means the server terminated abnormally

数据库.yml

production:
adapter: postgresql
encoding: unicode
database: myapp
port: 5432
pool: 5
username: username
password: password
reconnect: true

请任何人解释这个错误的原因以及如何避免它:

Error while reserving job: PG::ConnectionBad: PQconsumeInput() server closed the connection unexpectedly

更新:

我相信这个问题与延迟作业无关,因为我在执行一些正常的数据库查询时遇到了同样的错误。所以 DB 出于某种原因正在重新启动,这就是延迟作业服务停止的原因。

根据@LaurenzAlbe 的评论,以下是在 /var/log/postgresql/postgresql-9.3-main.log 中发现的一些问题:

LOG:  connection received: host=10.10.10.15 port=57322
LOG: replication connection authorized: user=MyDBUser
FATAL: must be superuser or replication role to start walsender
LOG: could not receive data from client: Connection reset by peer
LOG: disconnection: session time: 0:06:18.911 user=MyDBUser database=MyDB host=127.0.0.1 port=34040
./systemd: 36: kill: Operation not permitted
WARNING: skipping "delayed_jobs" --- only table or database owner can analyze it

最佳答案

经过一些研究,我认为延迟作业存在内存泄漏问题,使用 config.cache_classes = true 解决了这个问题,因为延迟作业会时不时地重新加载类。

我遇到了同样的问题,延迟的作业进程使用了​​超过 90%+ 的内存并且它因同样的错误而崩溃,即使我有缓存的类,但我在没有 RAILS_ENV 的情况下运行延迟的作业,这导致他们在开发中加载并忽略其他环境设置。

关于ruby-on-rails - 保留作业时出错:PG::ConnectionBad: PQconsumeInput() 服务器意外关闭了连接,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/48981963/
