在 Heroku 上生成 gem - “PGError：服务器意外关闭了连接”
我在 Rails 3 应用程序中使用 Spawn gem - 它是 https://github.com 上的rails3-adapted fork /rfc2822/spawn
我的应用程序部署在heroku上，当我尝试生成时出现此失败：
app[web.1]: ### ../controllers/messages_controller.rb:10:in `create_message': About to spawn
app[web.1]: spawn> parent PID = 1
app[web.1]: spawn> child PID = 49
app[web.1]: ### ../controllers/messages_controller.rb:17:in `create_message': After spawn
app[web.1]: Task Load (1.2ms) SELECT "tasks".* FROM "tasks" WHERE "tasks"."id" = 80 LIMIT 1
app[web.1]: PGError: server closed the connection unexpectedly
app[web.1]: This probably means the server terminated abnormally
app[web.1]: before or while processing the request.
我的 config/database.yml 中有此选项，遵循生成文档：
reconnect: true
您认为它与此有关吗？
有点不知所措......在我调查之前，有人知道是什么原因造成的吗？ 干杯，最大
I'm using the Spawn gem in a rails 3 app - it's the rails3-adapted fork at https://github.com/rfc2822/spawn
My app is deployed on heroku, and when i tried to spawn i get this failure:
app[web.1]: ### ../controllers/messages_controller.rb:10:in `create_message': About to spawn
app[web.1]: spawn> parent PID = 1
app[web.1]: spawn> child PID = 49
app[web.1]: ### ../controllers/messages_controller.rb:17:in `create_message': After spawn
app[web.1]: Task Load (1.2ms) SELECT "tasks".* FROM "tasks" WHERE "tasks"."id" = 80 LIMIT 1
app[web.1]: PGError: server closed the connection unexpectedly
app[web.1]: This probably means the server terminated abnormally
app[web.1]: before or while processing the request.
I have this option in my config/database.yml, following the recommendation of the spawn documentation:
reconnect: true
Is it connected to this do you think?
Bit at a loss with this... before i go investigating, does anyone know what's causing this?
cheers, max

我最终使用了 Girl_friday gem，这是一个简单的分叉队列系统。这对我来说非常有效。
I ended up using the girl_friday gem instead, which is a simple forked-queue system. It worked great for me.
