Question

我遇到了一个真正的大问题。我的应用程序正在进行几千个SQL查询，然后突然发生此错误。如果我直接通过rake任务或rails控制台执行我的代码，它就没有什么区别。

有谁知道这意味着什么？从未见过与rails logger相关的错误。

ENV：
红宝石2.1.2
postgres 9.3
rails 4.1.5

Could not log "sql.active_record" event. SystemStackError: stack level too deep ["/Users  /ghostrifle/.rvm/gems/ruby-2.1.2/gems/activesupport-4.1.5/lib/active_support/tagged_logging.rb:46"]
SystemStackError: stack level too deep
from /Users/ghostrifle/.rvm/rubies/ruby-2.1.2/lib/ruby/2.1.0/irb/workspace.rb:86
Maybe IRB bug!

23个来电者之后会出现异常。

这里是对SystemStackError异常的检查

请问您能否显示导致此问题的代码。根据我的理解，您正在保留一个堆栈，您正在添加从数据库中提取的数据，但您可能没有将其初始化为[]。因此，每次运行代码时，数据都会堆积起来并最终导致此问题。

SystemStackError：堆栈级别太深--sql.active_record？
