1)独角兽似乎正在稳定地填满所有RAM,导致我手动删除工作.

2)由于某种原因,独角兽似乎正在产生额外的工人,尽管我指定了一定数量的工人(其中7人).这部分是导致RAM累积,这也导致我手动删除工作.

3)在我的情况下,零停机部署是不可靠的.有时它会接收到更改,有时候我会出现网关超时.每个部署变得非常紧张的情况.

我不喜欢使用Monit,因为它会杀死工人,而不用等待工人完成他们的要求.

那是正常的吗？使用Unicorn部署的其他人也有同样的问题,即RAM不可控制地增长？

工人的工人人数是否与所定义的工人人数不符合？

另一个选择是独角兽工人杀手,我将在阅读Unicorn Eating Memory后尝试.

微小的更新：

所以,新遗物告诉我记忆差不多是95％.所以我不得不杀了一个工人.有趣的是,如果从下图中可以看出,那个工人的记忆力会下降很多.

怎么了？

作为参考,这里是我的unicorn.rb和unicorn_init.sh.会有人告诉我,某处有错误.
