太陽黑子寶石中的SystemStackError（棧級太深）

我知道這是跟蹤最難的錯誤。這是發生了什麼事情：我正在做一個涉及太陽黑子搜索的請求。對於所有返回合理solr響應大小的請求，一切正常。對於那些Solr的響應超過1 MB的特定要求，我得到這個錯誤：太陽黑子寶石中的SystemStackError（棧級太深）

這是太陽黑子的錯誤？

更新：不，這是一個紅寶石虛擬機問題，我報告它here。

提交了[太陽黑子bug]（https://github.com/sunspot/sunspot/issues/395） – hammady 2013-04-08 08:51:21

你能否嘗試獲得完整的堆棧跟蹤，以及Solr的完整響應？ – 2013-04-08 22:02:27

上面的堆棧跟蹤是我可以從這種異常中獲得的最大值。完整的Solr響應可以在這裏找到（http://da.qcri.org/solr-response-46-70000.txt）。 – hammady 2013-04-10 08:32:51

我注意到你使用Ruby-1.9.2-P320，並且據報道，另一顆寶石（delayed_job的）類似的問題，即reloader.rb是導致SystemStackError：

幾個人（儘管不是每個人）在該線程報告它通過升級到Ruby 1.9.3修復，所以你可能想嘗試。

對不起，這並沒有解決問題，閾值大約是640 KB solr響應。問題直接與響應大小（或導致大小變化的方面限制） – hammady 2013-04-08 07:17:31
