挂着红宝石过程（红宝石1.8）

Question

使用：红宝石1.8.7（2009-06-12 PATCHLEVEL 174）[x86_64的Linux的]

我有一个红宝石批处理作业，在一排的最后两晚也挂大约在同一时间。

奇怪的是，当我在进程中执行kill -QUIT时，它将其释放并继续处理。

这里是堆栈的时候我送SIGQUIT：

我怀疑，从看代码即时得到某种轨道上的记录器僵局。有关如何解决问题的任何建议。也许有关轨道记录器折叠的一些事情。不知道为什么这将在最近几天开始......

我不知道你是否在你的日志上使用logrotate，但它可能是日志旋转和Rails.logger不能写任何东西更多。执行kill -QUIT将重新打开日志文件并继续处理。
