对于heroku上托管的Memory quota exceeded
应用程序,我经常收到此错误ruby on rails

我读了一篇博客,其中建议使用solution即set
WEB_CONCURRENCY
配置变量,但我不清楚。我在Heroku上的当前配置是:
配置/独角兽.rb
worker_processes Integer(ENV["WEB_CONCURRENCY"] || 3)
timeout 29
preload_app true
编辑:
工人代码

site = Site.find params['site_id']
if params["id"].present?
photo = Photo.find(params["id"])
if params['key'].present?
photo.key = params['key']
photo.remote_image_url = photo.image.direct_fog_url(:with_path => true)

请建议我如何计算
WEB_CONCURRENCY
的正确值。 最佳答案
看起来你同时使用minimagick和kraken来进行图像处理。如果你完全迁移到克拉肯,让他们处理你所有的图像操作,你不应该有一个问题的记忆你的工人。
删除所有版本,看看这是否提高了性能。
version :leisure_358x243, :if => :leisure_theme? do
process :resize_to_fill => [358,243]
end
如果你想坚持在你的工作人员身上处理图像,有比carrierwave minimagick更有效的库。看看carrierwave-vips。
关于ruby-on-rails - 在heroku上设置WEB_CONCURRENCY的公式是什么?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/27704827/
