SystemStackError：堆棧級別太深 - sql.active_record？

我遇到了一個真正的大問題。我的應用程序正在做幾千個SQL查詢，然後突然出現這個錯誤。如果我通過rake任務或rails控制檯直接執行我的代碼，這沒有什麼不同。SystemStackError：堆棧級別太深 - sql.active_record？

有誰知道這意味着什麼？從來沒有見過與軌道記錄器有關的這個錯誤。

ENV：
紅寶石2.1.2
的Postgres 9.3
軌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!

後23個呼叫者異常升高。

這裏的檢查SystemStackError例外

當這種情況開始發生時，會發生什麼特別的事情？你有沒有檢查你的代碼沒有無窮遞歸？看看這個http://dalibornasevic.com/posts/5-ruby-stack-level-too-deep-systemstackerror – dabadaba 2014-08-31 22:19:05

thnx的鏈接，我現在試着ulimit命令 – ghostrifle 2014-08-31 22:21:50

以及..我的堆棧大小是8192巨大..但即使通過「ulimit -s 16384」增加它並沒有幫助。同樣的錯誤，仍然有23個調用者 – ghostrifle 2014-08-31 22:25:12

的可否請你展示這是造成這個問題的代碼。根據我的理解，您正在保存一個堆棧，您正在添加從數據庫中獲取的數據，但可能您沒有將其初始化爲[]。因此，每次運行代碼時，數據都會堆積並最終導致此問題。

可能是你做了一些無限循環，比如如果你在before_update裏面調用update_attributes，它會創建一個無限循環，同樣的錯誤會被拋出'棧層太深'。你可以弄明白。查看你的代碼。 – abhsss96 2014-10-10 17:56:10
